INTRODUCTION
Nowadays, literacy is crucial for humansAo live .
The mathematical literacy context is different from the mathematical-context .
Mathematics can be applied in various settings whereas mathematical literacy can be used to analyze each meaning quantitatively.
The domain of mathematics depends on the ability to understand rules, procedures and mathematical concepts that are increasingly abstract.
it is different from mathematical literacy .
Mathematical literacy aims to foster students with an ability to become active citizens participating in the present and future events because mathematically literate citizens possess an awareness of dynamic changes occurred and the need of long-life learning .
Mathematical literacy is the ability to interpret, formulate and utilize mathematics in various contexts including the use of concepts, procedures, and facts in mathematics that can develop the knowledge and confidence to think critically, logically and mathematically in interpreting and analyzing and solving problems of a day-to-day phenomenon to prepare individuals to face the challenges of life .
Generally, literacy has four aspects, namely reading, writing, speaking, and listening .
, however, this study focuses on reading and writing mathematical models.
Mathematical reading is an active process requiring unique and specialized skills to understand the meaning of mathematical language, especially in solving word problems and interpreting systematic graphs, signs, and mathematical symbols .

reading might help students to understand the meaning contained in a passage and increase the studentsAo opportunity to critically learn and think thus they become capable long-life independent learners.
Another aspect is writing which is a combination of several early reading skills involving several simultaneously functioned cognitive and physical processes .
, .
Mathematical writing is an individual activity in composing ideas through language in writing form using mathematical symbols so that targeted readers can understand it.
Mathematical literacy, as a stand-alone literacy, has three aspects: interpret, formulate, and employe .
Moreover, in its implementation in mathematical learning, mathematical literacy has five standard processes, namely Problem Solving.
Reasoning and Proof.
Communication.
Connections, and Representation .
It means mathematical literacy has a connection with the ability to apply mathematics to overcome daily problems.
One of the standard mathematical learning processes is problem-solving or the IndividualAos ability, in high-level cognitive aspects that require more basic skills, to find a possible solution to achieve unknown goals or challenging-to-be achieved goals .
, .
The ability in problem-solving might facilitate students to understand mathematics involving processes of designing, evaluating, and implementing strategies .
, .
The problem-solving-ability does not only rely on standard-relevant knowledge but also information that might help students to choose or determine the right answer by guessing the possible right answers by using some relevant strategies .
, .
Students are not only required to get the correct conclusion but also to use strategies to obtain the final results or outcomes.
The final results are crucial, but what is more significant is the process in drawing the conclusion, because it fosters studentsAo ability in recognizing or determining their thinking-process patterns in learning.
The main objective of learning mathematics is that students have the ability to solving various problems .
Problem-solving is not only the goal of mathematics learning, but also a means to achieve certain goals .
Moreover, the ability in problem-solving is an inseparable integral part of mathematics Thus, modern education should be able to educate and prepare students to become individuals with problem-solving ability.
, .
The problem-solving ability has four indicators as measurements:
understanding problems, formulating mathematical models, applying relevant solution strategies, and checking processes and results .
, .
The fact that Indonesian students take a position in 50 of 55 countries in the mathematical literacy, based on TIMSS 2015, indicates that Indonesia is still in a low category .
It leads to the necessity of reviewing Indonesia mathematical literacy to determine the reason behind such a case.
Mathematical literacy in mathematics learning is a standard ability required to be mastered by students to develop and improve their competency in other more-advanced mathematical skills.
The individualsAo ability to communicate and explain the phenomena they faced utilizing mathematical concepts is significantly preferred in mathematical By adopting the previous research conducted by TIMSS, this study aims to analyze the mathematical literacy of the 5th grade of primary school students viewed from the mathematical problem-solving abilities of students at SD Muhammadiyah Condongcatur.
RESEARCH METHOD
This research is a quantitative descriptive study with focus analysis is the problem-solving ability in mathematical literacy of grade 5 students.
Mathematical literacy is analyzed based on the results of the studentsAo test scores.
Furthermore, the results are then categorized into five categories: very high, high, medium, low, and very low.
Such categorization is based on the normative standard deviation reference as shown in Table 1 .

RESULTS AND ANALYSIS
Based on the observations, regardless of the participantsAo level in mathematical literacy, several students are struggling in interpreting the problem in the mathematical literacy test.
It might be because they are not familiar with the mathematical literacy problem adopted PISA questions.
they are more familiar with closed characteristics test items.
Related to time allocation, 70 minutes given are seemly sufficient time to answer five given questions.
It means that each student solved one problem on average within 14 minutes.
The percentage of the number of 5 th-grade students in each category based on the test results is presented in Figure 1.

There are only 9% of students are categorized as the very low students.
Move to the AoemployAo indicators, and there are only 14% of students are in the very high category whereas 23% of them are in the high category.
20% of participants are classified as moderates whereas the majority of them .
%) as the low.
Besides, the remaining 14% of students are included in the very low category.
It can be concluded that the higher the ability category of students, the higher their tendency to answer questions correctly and vice versa.
Such result aligns with a study conducted by Mistiani .
that found the higher the ability of the participants to more chances they correctly answer the test items.
in the very high category, the majority of students correctly answer questions.
It shows that students in this category do not experience significant difficulties in solving the given questions.
Based on the previous explanations, it can be concluded that geometry material is quite challenging material for elementary school students.
It is because the majority of students in the low to very high categories gave incorrect answers incorrectly.
Besides, they might find difficulties in geometry because most students have not understood the concepts of geometry.
It can be seen their behavior in incorrectly mismatching the formula of geometries.
a number of students often use a broad formula to measure mobile problems or vice versa.
Following is some conclusions drawn based on the students' answers in their answer sheets.
Question no.
1 for AoformulateAo indicator in patterns and algebras The data from studentsAo answer sheets for the question number 1 indicate that there are some difficulties encountered by students in solving questions, including: .
students have not been able to understand the problem thus, the answers given are irrelevant, .
students do not follow the directions provided in the question, hence some of them do not use the correct patterns.
Question no.
1 asked students to find the number of white tiles using a pattern .
n this case is squar.
not only using information that the number of blue tiles is 36 tiles which leads some of them to assume that 36 blue tiles can be formed into a rectangle.

2 for AointerpretAo indicator in statistical and opportunities The studentsAo answer sheets for question number 2 show that there are some difficulties encountered by students in solving questions, including: .
students have not been able to understand the problem thus the answers given are irrelevant.
Students did not follow the direction or information provided in the question thus that some students did not sum up all the book sales every month.
The students were asked the total sales of books each month, yet students discarded the information needed.
However, students are right in calculating total book sales in January and March but are wrong in estimating total book sales in February.
Question no.
3 for AoemployAo indicator in numbers The data from studentsAo answer sheets for question number 1 indicate that there are some difficulties encountered by students in solving questions, including: .
students have not been able to understand the problem thus, that the answers given are irrelevant to the questions, .
students did not follow the information or direction provided in the question, thus some students guessed each number of chicken legs and goatsAo feet with a total of 88 feet regardless of the number of goats and chickens .
Learners were asked to find the number of goats and chickens using information that there are 30 chickens and goats with a total number of feet are 88.
Some students only pay attention to the total legs of chickens and goats and ignore the number of chickens and goats in the cage.
Question no.
4 for AoemployAo indicator in measurement The studentsAo answer sheets for question number 4 indicate that there are some difficulties encountered by students in solving questions, including: .
students have not been able to understand the problem thus the answers given are irrelevant to the question, .
students did not follow the information provided in the question, so that some students were tricked by the weight of kerosene sold.
Learners were asked to find the weight of the barrel without kerosene, yet most students divided the weight of kerosene into barrels to two.
Question no.
5 for AoformulateAo indicator in geometry The studentsAo answer sheets for question number 5 indicate that there are some difficulties encountered by students in solving questions, including: .
students have not been able to understand the problem, so the answers given are irrelevant to the question, .
students did not follow the information provided in the question, so that some students did not compare one area to another.
The problem was to find the maximum area of the existing tour, but students discarded the information needed.
they did not compare the area thus the information of whether or not the area produced by the students was the maximum area is hardly be determined.
CONCLUSION
Mathematical Literacy of Grade 5 at SD Muhammadiyah Condongcatur is indicated in the high It is determined by their ability to solve mathematical problems that included in the high category.
Students have been able to understand problems and answered the questions regarding given and needed information by using logic to formulate and describe the problem models, choose the most appropriate solution to solve the issues, and draw the possible solutions guesses and verify the possible solutions.
