There are 4 boxes total all with equal number of dots. How many dots total? Simple non dyslexia math no rules is 2+2x4. 2+2=4 x4=16. We read and write L to R so why is this so hard to understand. Is it to easy like spelling fone we have to over complicate it with pH.

I applaud you having your students work through the process and then explain their reasoning. This is a great example of IB learning at its best!

I did want to let you know that the math problem pictured showing 3^2 + 4 × 7 + (3 × 2) has 3^2 evaluated as 9 when it is 27, since we know that exponents is just a short-hand version of multiplying the same base term. So yeah, from one tutor/teacher to another, I wanted to share that correction, and that problem then really comes across clearly as it relates to and supports your helpful explanation. :) Gabbynoreply@blogger.com
