Math for little kids is about laying a strong foundation. They might know what number 10 is, but number 10 is more than the name it holds. Truly understanding a number requires the ability to compose and decompose it. Read more about First Math Lessons here.  

What you need

  • LEGO pieces to build a two-level house
  • 10 LEGO characters

What to do

Start by building a LEGO house that has two floors.

When the house is built ask your kids to place all the LEGO characters inside. Say, “I noticed you placed two people on the first floor and eight on the second.”  

After discussing the placement for some time, say, “”Right now you have 2 people on the top floor and 8 people on the bottom floor. Let’s write it down 2+8=  What’s the total number of LEGO men?” Give them time to think.

“Can you find more than one way to place LEGO people inside the house?

Decomposition is a skill that requires practice.  #math #LEGO If your child is confused, prompt with, “What if this LEGO man feels dizzy and wants to move down from the second floor. How many men do we have on each floor now? What if this repairman needs to go upstairs to fix the bathtub? How many LEGO men on each floor now? What if Superman wants to help the repairman and goes upstairs too? How many now?” Write it all down.  

In this lesson children will be decomposing number 10 with LEGO people. Decomposition is a skill that requires practice. In earlier lesson we decomposed number 5, today we are moving up to 10.

  5. This is a great way to break down math for kids! :] (Hooray for the use of legos!) My friend works at a company that does after-school programs for kids that uses legos to help them with learning different things–I just met up with her today for brunch, so I was reminded of that. :]!

  6. […] Once your child learns how to count to 10, it’s time for decomposition.  Decomposition is a fancy word that means breaking down the numbers into their subparts.  Eventually, when kids can count to 100, they will be decomposing numbers into tens and ones.  But for now they only need to understand that numbers can be created using a variety of addends.  1+4, 2+3, and 5+0 all equal 5.  In this lesson, children need to find all the different ways to make number 5, so that they can have 5 candles on their cake.  It’s a very simple decomposition practice that is made fun with LEGOs.  Read more about First Math Lessons here.  If you are ready to move on to decomposing number 10, go here.
