At our last math community meeting teachers were given an opportunity to explore the provocation shown above. This provocation was provided to support wonder, curiosity, creativity and multiple opportunities for computation. Teachers were able to create designs with addition, and multiplication using one of my favorite computation manipulatives…Cuisenaire rods.
I chose this activity and these manipulatives for many reasons.
- It allows students to explore part-part-whole thinking
- It provides opportunities for multiple computations in an engaging way
- It brings creativity, and design into mathematics
- It allows for collaboration, and conversation
- Students can discover relationship, and multiple interpretations
After our professional exploration many teachers took this activity back to their classrooms and shared it with their young mathematicians. Below are some examples of what the students came up with in classrooms.
As a follow up students can bridge the concrete to abstract continuum by recording their computations/designs pictorially and abstractly on a sheet. Initially, recording sheets could have pictures of coloured rods to match the concrete representations the students created. As students progress in their level of abstraction they can switch to just marking the value on the rod. Abstractly, they would record the equation their design represents.
Below are some supports that can help you incorporate Cuisenaire rods into your classroom.
