It’s important to understand that children should master the combinations for one number before moving on to the next. It means that while students may still need objects and/or pictures for the combinations for the numbers above five, they should know all the combinations for the numbers up to five automatically by the end of Kindergarten.ĭecompose Numbers in More than One Way Determining a Child’s Target Number The skill is really no different than the first standard. In our number system, ten is a special number and that’s why it gets a specific standard.Students should work on one target number at a time and master all of the combinations for that number before moving on to the next number. Do not overlook the fact that students need to acquire this skill using objects and pictures before recording each decomposition as an equation or drawing. It can also be broken apart (decomposed) into those same parts. ![]() Five can be made (composed) of 0 and 5, 1 and 4, or 2 and 3. The first standard says that for every number up through ten, children should know all the different ways to make (compose) or break apart (decompose) that number.Then scroll down for additional information and for free activities to practice the skills. Read below for a translation of each of the standards. In other words, each standard builds on the previous one. Need that in plain English? First of all, understand that they are sequential. I am in Texas, for example, and you will find very similar standards in our TEKS.ĭecompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).įor any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation. Even if you are not in a state that follows the CCMS, your state probably has similar standards in Kindergarten. There is no additional cost to you, and I only link to books and products that I personally recommend.įirst, let’s take a look at the Kindergarten Common Core Math Standards (CCMS) related to developing fact fluency. ![]() This post contains affiliate links, which simply means that when you use my link and purchase a product, I receive a small commission. What does Kindergarten math look like? What are the essential skills that every Kindergarten student should master prior to Grade 1? Believe it or not, fact fluency starts in Kindergarten when students learn to compose and decompose numbers! Now, before you whip out those flashcards (the way many of us learned our “facts”) or start cursing me about how children are losing their childhood, read on to see exactly what I mean and for Kindergarten games and activities that are more fun than work.
