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

[Ms.Burri @MsBurriOCSB]

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

[Lisa Dallas 🍏 @MrsDallasOCSB]

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

[Dan Hoang @MrHoangOCSB]

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

Answers from a math school!

[Susan Drysdale @SdrysdaleSusan]

What does math taste like? I love these answers from the students at Clifton! @dduff77 @TracyCh4386002

Great connection to Double Number Line and PartS Whole Box!

[Leanne Kennedy Stredwick @LeanneStredwick]

Working with grade five students today! Some fantastic thinking around ratios, proportion, patterning and decomposition!

[Doug Duff @dduff77]

Wow so many examples of great thinking.

[Doug Duff @dduff77]

Thanks St Catherine staff and students. So many great moments for me. Such an invitational culture.

[St. Catherine PVNC @StCatPVNC]

It was a pleasure to host Doug Duff at our school yesterday and engage in rich conversations about how to help all learners succeed in math. @dduff77 @JeannieArmstr20

[Doug Duff @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.

[Doug Duff @dduff77]

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.

[🧮💭Sara Boone 🧠📊 @SaraMBoone]

Cuisenaire rod fraction exploration today, building fraction sense. @dduff77 #iteachmath

[Michelle McCarron (she/her) @MCubedCCRCEMATH]

@dduff77

[Doug Duff @dduff77]

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

[Kathryn Mackie @KathrynMackie3]

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

[Doug Duff @dduff77]

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