This research aims to determine the increase in student learning activities with Team Games Tournament (TGT) type cooperative learning at MTs YPKS Padangsidimpuan. This type of research is classroom action research. The object of this research is to increase student learning activities through TGT type cooperative learning in class VIII MTs YPKS Padangsidimpuan. The research subjects were 33 students in class VIII-4. /friend's explanation was 18%, the activity of reading student books/LKS was 2.5%, the activity of noting the explanation of the teacher/friend/from the book was 12%. , distribution activities by 16%, and activities that are not relevant to learning by 51%. So it was found that student activities for each activity category had not yet reached the ideal activity criteria. The results of the analysis after being given action II were from the results of observing the activity of listening/paying attention to the teacher/friend's explanation by 46%, the activity of reading student books/LKS by 7.5%, the activity of noting the teacher/friend's explanation/from the book by 10.5%, the activity division was 19%, and activities that were not relevant to learning were 17%. This shows that student activities for the four activity categories have experienced improvement, but have met the ideal activity criteria

Numeracy literacy is an essential competence for solving everyday problems, yet the numeracy literacy of Indonesian students remains low and mathematics learning is still dominated by lectures. This study aims to determine the effect of the Case-Based Learning model assisted by Wordwall media on the numeracy literacy ability of Grade XI students at State Senior High School 1 Batang Toru on the topic of circles. The study used a quantitative approach with a quasi-experimental method and a Nonequivalent Control Group Design. The sample was determined by purposive sampling, consisting of class XI-7 as the experimental class with 35 students and class XI-5 as the control class with 34 students. Data were collected using a numeracy literacy test of five essay items that were valid and reliable, with a Cronbach's Alpha of 0.823. The data were analyzed using the Liliefors normality test, the Fisher homogeneity test, and a separate-variance t-test. The mean posttest score of the experimental class was 94.86, higher than that of the control class at 82.94, with score increases of 28.00 and 13.82 points, respectively. The variances of the two classes were not homogeneous, so the t-test used separate variances. The t-count of 7.134 was greater than the t-table of 1.674 at a significance level of 0.05 and 54 degrees of freedom, so the alternative hypothesis was accepted. Therefore, the Case-Based Learning model assisted by Wordwall has a significant effect on students' numeracy literacy ability.

Learning activity and learning outcomes in mathematics remain low, partly because learning is dominated by lectures with conventional media. This study aims to determine the effect of Canva-based visual learning media on the learning activity and mathematics learning outcomes of Grade XI students at State Senior High School 1 Batang Toru on the topic of circles. The study used a quantitative approach with a quasi-experimental method and a Pretest-Posttest Control Group Design. The sample consisted of class XI-3 as the experimental class with 35 students and class XI-2 as the control class with 35 students. The instruments were a learning outcome test of five essay items, which was valid and reliable with a Cronbach's Alpha of 0.9488, and a learning activity observation sheet. The data were analyzed using the Liliefors normality test, the F homogeneity test, a one-tailed t-test, and the normalized gain. The mean posttest score of the experimental class was 90.86, higher than that of the control class at 85.71. The average normalized gain was 72.38% (high category) for the experimental class and 58.43% (moderate category) for the control class. The t-count of 2.9043 was greater than the t-table of 1.667 at a significance level of 0.05, so the null hypothesis was rejected. The learning activity of the experimental class was categorized as active to very active. Therefore, the mathematics learning outcomes of students who used Canva-based visual learning media were significantly higher than those of students who used conventional media.
