[Junior Arithmetic Olympics]Puzzle problems that even 5th graders can solve[Arithmetic to be solved by elementary school students]

[Difficulty: ★★★☆☆]This is a problem for the 2022 Junior Math Olympics. ▼Important solution points ① First, let’s check that the areas of the two figures separated by the diagonal line are the same for the parallelogram. Then mark the shapes with the same area. ② After marking the parts with the same area, let’s see which areas are equal to each other. You should understand a lot. I think it was an interesting problem, like a puzzle, where the area was found one after another. I think it’s hard to solve it within the time limit. I think it’s an interesting problem to solve simply out of curiosity. It was an issue that I really wanted to fix. ▼ Click here for each SNS of manavisquare (Manabi Square) HP https://manavigate.co.jp/ twitter https://twitter.com/manavisquare Yuta Sugato twitter https://twitter.com/mrkeiosfc16no1 ▼ Feel free to contact us please give me! kikaku@mnsq.jp
