These grade 3 students in Ms. Boisvenue’s class are using number lines to solve subtraction problems! It’s great to see a variety of strategies to build confidence @StBrAndreOCSB #ocsbMath @dduff77

Yes, and If you use you 1/8th benchmark or partition into eighths. You could estimate there are 8 68's + 1/2 of 68. So a bit more than 8 1/2 times.

Look. closely at the Embedded Quantity Decomposition. Nice work transferring to angles - which are PartS of a Whole!

Great to see the number line at the bottom of the PartS Whole Box. WOW! Benchmarks are there - especially when you scale up 100x. From a bit less than 1400, 700 is 1/2, 350 is 1/4….important practice of estimating with hundredths and 1000’s.

Working at a #BWDSB school today - the prompt "Find two fractions with different denominators that are close together" - Great use of double number lines
