Learning the Facts

Students will learn these addition and subtraction facts through frequent and repeated use. In school, we will be playing lots of games that help students learn particular groups of facts. Students will also play some of these games for homework. We'll also be using Fact Cards like the one below.

Students use these cards to practice their facts and sort them into two envelopes— “Facts I Know” and “Facts I Am Still Working On.” We think a lot about ways to remember the facts that students find difficult. For example, your child might write, “Think 5 + 5 + 3” as a clue for solving 5 + 8.

In addition to using the facts frequently, students will focus on the numbers and relationships involved. That way, if students forget a fact, they can still solve the problem quickly and efficiently. For example, students might use the following strategies:

  • • “8 + 5 is the same as 8 + 2, which is 10, and 3 more, which is 13.”

  • • “7 + 9 is like 7 + 10, just one less. So it's 16.”

Again, thank you for your interest and support.
