3. Diverse questions: The calculator is equipped with a rich question bank, including addition, subtraction, multiplication, division, four arithmetic operations, fraction operations, etc., which can meet the needs of different age groups and learning stages.
Second, how does the calculator become a good helper in learning? 1. Assisting in math class learning: In math class, teachers usually assign some arithmetic exercises. Using the calculator, students can complete a large number of exercises in a short time to improve their calculation ability. At the same time, the calculator can automatically correct homework, so that teachers can better understand students' learning situation. 2. Improving autonomous learning ability: The calculator has the function of autonomous learning. Students can freely choose questions for practice according to their own learning progress and needs. This can not only improve students' interest and enthusiasm in learning, but also cultivate their autonomous learning ability. 3. Strengthening memory and understanding: Through repeated practice on the calculator, students can strengthen their memory and understanding of mathematical knowledge. At the same time, the calculator can also generate a wrong question set to help students focus on their weak links for key practice. Third, case analysis: Xiaoming is a fourth-grade student who has always struggled with mathematical calculation ability. Since his parents bought him a calculator, his mathematical calculation ability has improved significantly. He uses the calculator for independent learning and practice, gradually mastering the four arithmetic operations and fraction operations in mathematics. In math class, he can quickly and accurately complete teacher's assignments and practice questions, which has received teacher's praise and classmates' recognition.
