3 quick questions from earlier weeks · about 3 minutes
- 18 − 9 = ? Facts to 20
- How much money is 1 quarter, 1 dime, 3 nickels and 2 pennies? Week 34
- 534 + 150 = ? Week 32
Objective: Students will identify and draw triangles, quadrilaterals, pentagons, hexagons, and cubes by number of sides, angles, and faces (2.G.A.1).
- 10 min — Warm-Up: Read 7:20 and 12:55 on the paper clock and total 2 quarters, 1 dime, 3 pennies (63 cents). Then go on a 60-second shape hunt: name five flat shapes in the room and how many sides each has.
- 15 min — Mini-Lesson: Review shape attributes (first taught Week 27). Draw a triangle, a square, a rectangle, a rhombus, a pentagon, and a hexagon. For each, count sides and corners (angles) aloud and record in a chart. Hold up a cereal box and a dice: count faces (6) and say why they are cubes or not (a cube has six square faces).
- 15 min — Practice: Attribute riddles: your child draws the shape you describe with a ruler. 'I have 4 sides, all the same length, and 4 square corners.' 'I have 5 sides.' 'I have 3 sides and one square corner.' 'I have 6 sides.' 'I have 4 sides but they are not all equal.' Then they write two riddles for you.
- 5 min — Wrap-Up: Ask: 'Are all squares quadrilaterals? Are all quadrilaterals squares?' File the attribute chart in the portfolio.
