Shapes equal shares test answers: worked solutions
Question 1 – Name the shapes [2 pts]
- Shape A has 5 sides: a pentagon.
- Shape B has 4 sides.
Scoring: 1 point for pentagon. 1 point for 4 sides.
Question 2 – Cube faces [2 pts]
- 3 faces show and 3 are hidden: \(3 + 3 = 6\). A cube has 6 faces.
- Each face is a square.
Scoring: 1 point for 6. 1 point for square.
Question 3 – Check the claim [2 pts]
No. A pentagon has 5 sides and 5 angles. A shape with 4 sides and 4 angles is a quadrilateral.
Scoring: 1 point for saying no. 1 point for a correct reason (a pentagon has 5 sides, or the shape is a quadrilateral).
Question 4 – Rows and columns [2 pts]
- 4 rows and 5 columns.
- \(5 + 5 + 5 + 5 = 20\), so 20 squares.
Scoring: 1 point for 4 rows and 5 columns. 1 point for a correct addition sentence (4 fives).
Question 5 – Which shows thirds [2 pts]
- Rectangle C has 3 equal shares, so it shows thirds.
- Rectangle B has the fewest shares (2), so its halves are the biggest.
Scoring: 1 point for C. 1 point for B.
Question 6 – Equal shares or not [2 pts]
No. The rectangle has 3 parts, but the parts are not the same size. The left part is bigger than each of the other two parts.
Scoring: 1 point for no. 1 point for explaining that the parts are not equal in size.
Question 7 – Cornbread pieces [2 pts]
- \(1 + 1 = 2\), so they ate 2 fourths.
- \(4 – 2 = 2\), so 2 fourths are left.
Scoring: 1 point for each correct part.
Question 8 – Shade the shares [3 pts]
- The rectangle has 3 equal columns. Shade one column (2 squares); any one column is correct.
- 2 squares are shaded, because \(6 \div 3 = 2\).
- The other 2 columns are not shaded: two thirds.
Scoring: 1 point for one full column shaded. 1 point for 2 squares. 1 point for two thirds.
Question 9 – Compare the sandwiches [3 pts]
- Sofia’s shares are halves. Diego’s shares are fourths.
- Fewer shares means bigger shares, so Sofia’s pieces are bigger.
- 4 fourths make a whole, so 4 pieces.
Scoring: 1 point for halves and fourths. 1 point for Sofia. 1 point for 4.
Total score
20 points
Key facts behind this shapes equal shares test answers

- A polygon has the same number of angles as sides.
- A cube has 6 faces and every face is a square.
- Count a rectangle of squares by rows: add the number in one row once for each row.
- 2 halves, 3 thirds, or 4 fourths each make one whole, and equal shares are the same size.
