Motivation from performance - what a group of mathkids! Amazing job Ms. Burri.

Thank you @dduff77 for coming to our classroom today! We had a great time learning how to use relational rods to represent different parts and whole numbers of fractions. 🤩 #OcsbMath @StClareOCSB

The Grade 6s @StLukeOttawa learned how Cuisenaire rods can be used to work on algebra problems. They modelled some equalities and then subbed values into algebraic expressions to solve them! #ocsbMath #Cuisenaire #ocsb @dduff77

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.

Fabulous flexibility with rods. Great how you worked in Fractions greater than 1. Now we can visualize all the adding and difference between fractions with unlike denominators.

Gr.8 students at @NG_Academy used rods to build an understanding of linear relationships, and to see connections between y=3x and y=3x 2. A parts-whole model allows them to think flexibly about ways to describe the relationships bw variables! @CCRCE_NS @CcrceM @MCubedCCRCEMATH

This is great! Look at all the thinking as they uncover number relationships and examine PartS Whole reasoning.

Students school-wide are working with Cuisenaire rods to develop additive reasoning, a need identified through Math Up Leadership common tasks. This can unlock foundational concepts for students and gives exposure and practice with a linear model. Go @NG_Academy! @CCRCE_NS

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