not additive thinking, groups must be equal, additive thinking is 3 + 4 (groups are not necessarily equal) but multiplicative thinking requires the groups to be equal e.g. 3 x 4.

LAB Linear Algebra Blocks

Decimals can be a tricky topic for students. Here is a short video to show the power of using Linear Algebra Blocks (LAB or Decimal pipes or decipipes) to support your students’ understanding of decimals. I think every classroom should have these readily available for students to use.

If you would like your own set of decimal pipes please see the Products page.

I have also included a video I took many years ago in my classroom to show you how I used my one set of decimal pipes in a “fishbowl” scenario to introduce multiplying decimals.


Using a number slider to divide by 10

An introduction to dividing by 10 using a number slider. The free downloadable template for the number slider can be found at TES resources (UK or Aus) or TPT (teachers pay teachers in the US). This is a great resource for teaching multiplying and dividing by powers of ten. Check out the You Tube clip that I made.
