Term 2: 

1) Geometry - 3-D objects and 2-D shapes

Grade 4 and 5 students this term will:
• describe and construct rectangular and triangular prisms.
• describe and provide examples of edges and faces of 3-D objects, and sides of 2-D shapes that are 
 -parallel 
 -intersecting 
 -perpendicular 
 -vertical 
 -horizontal
• identify and sort quadrilaterals including:

-rectangles
-squares
-trapezoids
-parallelograms
-rhombuses
according to their attributes

Project: Designing a Popsicle Stick Bridge

Designing Bridges - Students will design their own bridge using popsicles sticks. They need to consider the different geometric shapes they will use to create a strong and stable bridge. Students will learn that triangles are strong. A triangle spreads out weight and is more stable than a simple rectangle or square support. Students will need to take in to consideration all the loads and forces acting on the bridge.

2) Measurement - Length, Perimeter, Area, Volume and Capacity

Grade 4 students this term will:
• demonstrate an understanding of area of regular and irregular 2-D shapes by 
• recognizing that area is measured in square units 
• selecting and justifying referents for the units cm2 or m2 
• estimating area by using referents for cm2 or m2 
• determining and recording area (cm2 or m2) 
 • constructing different rectangles for a given area (cm2 or m2) in order to demonstrate that many different rectangles may have the same area

Grade 5 students this term will:
• design and construct different rectangles given either perimeter or area, or both (whole numbers) and draw conclusions
• demonstrate an understanding of measuring length (mm) by selecting and justifying referents for the unit mm 
• modelling and describing the relationship between mm and cm units, and between mm and m units 
• demonstrate an understanding of volume by selecting and justifying referents for cm3 or m3 units 
• estimating volume by using referents for cm3 or m3 
• measuring and recording volume (cm3 or m3) 
• constructing rectangular prisms for a given volume 
• demonstrate an understanding of capacity by describing the relationship between mL and L 
• selecting and justifying referents for mL or L units 
• estimating capacity by using referents for mL or L 
• measuring and recording capacity (mL or L)
