1 inch, "3×8=24 inches", "4×6=24 inches" and so on. And multiply the numbers in your hand into a combination of 3 and 8, 4 and 6. You can also use division, such as combining arrays into "48÷2=24" and so on.
2. Multiply before adding or multiply before adding: Another common technique is to multiply before adding or multiply before adding. For example, when the numbers on the card face are 3, 6, 2 and 4 in turn, the result can be obtained by multiplying them first and then adding them, that is, 3×4+6×2- 12+ 12=24.
3. Use parentheses: The use of parentheses can change the order of operations and get different results. For example, you can try a combination of numbers in the form of "(3+6)×(2+4)=24".
4. Use special numbers: Some numbers can be combined to get 24 directly. For example, when the numbers on the card face are 1, 3, 8 and 12, the result of "8÷( 1-3/ 12)=24" can be obtained directly.
5. Explore various solutions: There are many solutions for 2 1 point games. You can try different combinations and operation sequences to explore more solutions.
Here are some math games that can help children learn to add, subtract, multiply and divide:
1. Math card game: Use the numbers and operators on the card to make children combine formulas equal to specific results. This can help them practice using operators and combining numbers.
2, math maze game: design a maze, each room in the maze has a math problem, children need to answer correctly to pass. This can exercise their computing ability and problem-solving ability.
3. Math contest games: Participating in math contests can stimulate children's interest in learning and improve their computing and problem-solving abilities. Some interesting math competitions can be organized so that children can learn and grow in the competitions.
4. Math jigsaw puzzle: Make numbers and operators into puzzles, and let children combine the correct formulas through puzzles. This can help them understand the relationship between numbers and the functions of operators.
