Chapter 5

Shapes & Patterns

How do I use concrete materials and drawings to understand and show understanding of fractions?
What attributes make up a shape?
Where in the real world can I find shapes?
How can objects be represented and compared using geometric attributes?

Students will know and understand:

identify, classify, and describe plane shapes
make same and different shapes
divide shapes into two and four equal parts
describe the whole as the sum of the parts
closed vs. open figures
sides, corners, faces
Rectangles, Square, Trapezoid, Triangle, Half-Circles, Quarter-Circles, Cubes, Prisms, Cones, Cylinders
2D vs 3D Shapes

Students Will:

Formative Test: Common

Upon completion of Unit 5:

1.G.A.1. Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size) ; build and draw shapes to possess defining attributes.
1.G.A.2. Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.
1.G.A.3. Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.
MP.1. Make sense of problems and persevere in solving them.
MP.2. Reason abstractly and quantitatively.
MP.3. Construct viable arguments and critique the reasoning of others.
MP.4. Model with mathematics.
MP.5. Use appropriate tools strategically.
MP.6. Attend to precision.
