#### Curriculum – Geometry and Spatial Sense

• Sorting and classifying 3-dimensional shapes by attributes
• Classifying 3-dimensional shapes by geometric properties
• Describing location using positional language
• Relating shapes to other shapes, to designs, and to figures
• Composing and decomposing shapes
• Recognizing transformations

#### Context

Children are briefly presented with a 3-D structure made of multilink cubes and they must then re-create the structure from memory.

#### Materials

• Pre-assembled figures made of multilink cubes (see photos of cube figures below)
• Bags of cubes (two colours) for each pair of students

#### Lesson Introduction

• Gather children in a semicircle with full view of teacher and provide them with multilink cubes.
• Briefly present students with a pre-assembled cube figure and show it for approximately 5 seconds.
• Invite students to first discuss what they saw and then to re-create the figure from memory.
• Repeat, presenting the figure for approximately 5 seconds each time until students have created what they think is the presented figure.
• Reveal the original figure and have students compare their figure to it, discussing strategies they used to remember the figure and build it.
• Repeat the exercise but with increasingly more complex structures.

#### Lesson

• Tell students they will be making a bird nest.
• Ask students to collect items they want to use into the plastic container.
• Ask students to shape it into a nest.
• Place the container in our outdoor environment where a nest would usually be found.

#### Closure

• Discuss what it was like making a nest – finding the pieces, constructing the nest, etc.
• Discuss whether it would be easier for birds to make nests and why
• Monitor the nests over the week and make observations: if any nests have been occupied, if any materials are missing etc.
