Do you do Santa with your children? There tends to be a lot of facebook posts going around lately about why you should or should not do it.

We have chosen to let our children know that Santa is a fictional character just like Batman or their favorite Paw Patrol character.

But just as our kiddos love anything Batman, Paw Patrol, or Lion, Witch and Wardrobe related, they love Santa.

Decomposing Numbers Kindergarten

With that love in mind, today I’m allowing my kindergartner to be Santa’s helper with this decomposing numbers game. Santa needs to have boxes packed with toys so that there will be a few Christmas presents under the tree before he arrives.

Each box only holds 10 toys, so my little kindergartner will be decomposing numbers to pack the boxes correctly.

Decompose Definition in Math

What does decomposing mean in math? Leslie from Kindergarten Works says, “Decomposing numbers means to break down numbers into their sub-parts.” What does that mean? It is simply helping children recognize that 13 is 1 ten and 3 ones. 10 +3 = 13

When teaching decomposing it is important for children to recognize two aspects of it.

  1. Have children use pictures, words, ten frames, blocks, or anything else to show the place values of each digit.
  2. Have children be able to create an expression to show that place value.

And that is exactly what this activity get our kiddos doing.
