I have created math talks for kindergarten, first grade, and second grade to increase engagement and promote independent thinkers. Math Talks: Something special happens when you sit down and do math talks, or number talks, with kids.There are different ways we can make the number 7, such as 1 and 6, 2 and 5, 3 and 4, 5 and 2, 6 and 1, or 7 and 0.” Instead of saying this is number 7, you could say “This is 7. When you teach numbers, talk about them as much as possible. Model, model, model: I can’t stress this enough.If you’re looking for teaching strategies for the older kids, check out Time for Learning Middle School Math. Therefore, let’s look at some tips to teach decomposing numbers in the younger grades. However, here on Little Learning Corner, I share tips and resources for early childhood, specializing in Kinder, grade one, and grade two.
#Compose and decompose numbers how to#
Learning how to decompose and compose numbers looks different in each grade. For example, kids will put together sets of objects, of smaller numbers, to make a complete set.ĭecomposing numbers is the ability to break down numbers into their sub-parts.ħ Different Ways to Teach Decomposing Numbers Let’s look a little closer at what this means, and how you can teach it to kids.Ĭomposing numbers is the ability to put two parts together to make a whole. If you have young children, or teach elementary school, you may know this as “part, part, whole”. In other words, it’s learning how to parts make a whole. Decomposing Numbersĭecomposing and composing numbers, in short, is the ability to break apart a given number and put it back together again.
I’m here to explain the difference between the two, and show different ways to build the students’ understanding of these early math concepts. To build a solid number sense, kids will learn about composing and decomposing numbers as early as kindergarten, and practice these critical skills in first grade, second grade, and beyond.
