3 quick questions from earlier weeks · about 3 minutes
- 6 + 9 = ? Facts to 20
- A bar graph of pets shows: cats 9, dogs 3, rabbits 6. How many pets in all? Week 26
- What time is it 15 minutes after 2:30? Week 24
Objective: Students will identify triangles, quadrilaterals, pentagons, and hexagons by counting sides and vertices (2.G.A.1).
- 10 min — Warm-Up: Spiral from Week 26: draw a small bar graph with squares 3, triangles 5, circles 2 and ask, 'How many more triangles than circles?' Then ask, 'What makes a triangle a triangle?' and listen for the number three.
- 15 min — Mini-Lesson: Draw a triangle, a quadrilateral, a pentagon, and a hexagon. For each, trace the sides with a finger while counting, then tap and count the vertices, the corners where two sides meet. Write the name and both counts under each: triangle 3 and 3, quadrilateral 4 and 4, pentagon 5 and 5, hexagon 6 and 6.
- 15 min — Practice: Your child builds each shape with toothpicks or straws on the table, using one stick per side, and records sides and vertices in a table. Then they make a wobbly, stretched version of each and confirm the counts stay the same.
- 5 min — Wrap-Up: Ask, 'Is a square a quadrilateral? Is a rectangle?' Guide your child to say yes because both have 4 sides and 4 vertices.
Materials: toothpicks or straws, paper, pencil
