Addition and Multiplication Strategies - The Triangles

The Triangles did something really exciting in math group today - we used an app called "Showme" to demonstrate different addition and multiplication strategies.

Keira, Elisa, Ashton, Spencer, Jaime and Sophie show how they can solve addition equations using the following strategies:
  • Rounding and Compensating Strategy - makes a calculation easier by rounding a number in the problem to a tidy number and then compensating by adding and/or subtracting the amount the number was rounded by.
  • The Place Value Strategy - partitioning numbers using place value (hundreds, tens, ones)
Samantha demonstrates how to solve multiplication equations by making equal groups of objects.

It's taken us a few weeks to get to this stage - whenever we learn a new strategy we always get the math equipment back out - place value blocks, popsicle sticks, number charts, counters. That way we really understand what we are doing when we manipulate the numbers. 

We were all a bit nervous about recording ourselves today (including Miss Chalmers!) so please be sure to leave an encouraging comment below :)

  3. Wow, this was amazing to watch and listen to. I really liked that I could hear you and see you writing the equation out!

    Well done everyone, you did not sound nervous at all.
