Mental computation

The research aimed to investigate the effectiveness of using mental Computation on developing some number sense skills in mathematics among third-grade primary students. The study followed the semi-experimental approach, The research sample consisted of (60) students male and female, who were distributed among two groups: the control group (30) students male and female and the experimental group (30) students male and female. The control group studied in the traditional way; the experimental group studied by using the computation strategies. The research's tools consisted of a 20-item number sense in a multiple format. The psychological properties of the test were verified, and appropriate statistical treatments were used to answer the research questions, The findings showed that the experimental group was superior over the control group with an arithmetic mean of (16.262) Whereas, the control group obtained an arithmetic mean of (12.771), and based on the results, the researcher recommended integrating mental Computation strategies into the developed mathematics curricula.

Dyslexic Students

To describe mental computation strategies of the dyslexic student in performing the addition and subtraction of 1-digit and 2-digit integer. Mental computation is a process of doing arithmetic calculations without using other tools. This strategy will help dyslexic students find more accurate and flexible solution while solving the arithmetic problem because it can minimize their weaknesses in terms of reading and writing. This research uses the qualitative approach. Data were collected by using a task-based interview for two dyslexic students. The results of this study indicate that dyslexic students use the spin-around strategy to solve the addition for the 1-digit number and the working from the right and from the left strategies to solve the addition for the 2-digit number. Meanwhile, to solve the subtraction problem, dyslexic students use think addition and counting back strategies for the 1-digit number and Working from The Right strategy for the 2-digit number.

Computation Speed

The aim of this study was to investigate the effects of kinesthetic educational game on students' mental computation speed and achievement. The participants were 63 students. The working group was divided into two separate groups as experimental and control groups. The pre-test developed by the researchers was applied to measure prior knowledge of the students in the beginning of the experimental process. In the following eight weeks, computer-based and kinesthetic educational games were applied to the experimental and control group. During playing the games, number of correct answers and completion time were recorded and the post-test was applied. According to results, the mathematical performance and mental computation speed of the experimental group is higher than the performance and speed of the control group. When the findings about the game completion time of experimental group evaluated, the time of the first game is longer than the time of the last game. And also, the scores of the last game is higher than the scores of the first game.
