What is half?

A THREE PART MATH LESSON

Cross Strand Learning:

Number Sense & Numeration:

• investigating fraction of a whole 

Geometric Relationships:

• Compose and decompose two-dimensional shapes
• Locate line of symmetry in a two-dimensional shape

Focus: What is half?

Minds On:

Identifier les formes géométriques, en faisant glisser le nom sur l'image correcte.

Activity # 1

The Minds On, was a whole group activity. The purpose of the activity was to refresh the students geometric math vocabulary from grade one.  Students had to identify the 2D shapes and drag the vocabulary over the matching image. This activity was done in Notebook on the Smartboard.  Together we practiced reading the vocabulary aloud.

Action:

Comment est-ce que tu peux couvrire une moitié de l'hexagone? Explique en utilisant Explain Everything.

In our class the students share 10 iPads, thus our Action activity was in groups of two or three.  To complete the task, students had to explore, using 2-D geometric shapes to cover half of a hexagon.  The next step was to take photos of their findings and record their thinking with the Explain Everything.

Consolidation:

Regarde les vidéos créer par les élèves et discute.

This part of the lesson is where lots of cool learning takes place.  The students are so proud to share their work and also excited to see what their peers have created.  

In the consolidation, as a group, we watched all the presentations  on the Smartboard.  (There was another step in there, I uploaded the presentations from Explain Everything to a shared folder in Google Drive).  The students immediately offered peer feedback and shared their thoughts with the class.  Students were able to pick up on criteria that was left out or  able to give an opinion is a positive way.  These videos are also great because students are able to see that there is more than one possible answer to the task.
