To turn a word problem into a number sentence, kids need to understand the language and concepts of math.
Think about this problem: “Trevor has two pencils. He buys three more pencils. How many pencils does he have in all?” Kids need to know that the phrase “in all” means adding together the two groups of pencils.
Some kids may have a hard time picturing this. You can make it more concrete by using coins, toothpicks, or other objects. Use them to form the two small groups, and then combine them into one group.
