Problem Solving Subtraction Grade 4 In the one part unknown structure, we know the total and one of the parts, but we are missing the other part. this is also commonly called a missing addend problem. we often solve this type of problem using subtraction, but a counting up strategy works well also. a really interesting structure is both parts unknown. The fourth section contains addition and subtraction word problems. we also have an addition and subtraction online quiz with numbers up to 20. the sheets involve different skills to solve and have been set out in different ways to give more variety and interest. the sheets are graded so that the easier ones are at the top. Here are five strategies to help students check their solutions. 1. use the inverse operation. for simpler problems, a quick and easy problem solving strategy is to use the inverse operation. for example, if the operation to solve a word problem is 56 ÷ 8 = 7 students can check the answer is correct by multiplying 8 × 7. Start with using base ten blocks, regardless of which grade level (2 5) you are teaching. place an age appropriate addition subtraction expression on the board and have students model it using base ten blocks. walk through the steps of adding subtracting using the blocks. students should be comfortable manipulating the base ten blocks without.
