Counting Objects and Cardinality: math test solutions, Kindergarten – download the PDF

1 Count and write / 4 pts

Plate A: count the stars: one, two, three, four, five, six, seven, eight. There are \( 8 \) stars (1 pt).

Plate B: counting on past ten gives thirteen, so there are \( 13 \) counters (1 pt).

Plate C is empty, so there are \( 0 \) objects (1 pt).

For plate A the last word is eight, and it tells how many (1 pt).

2 Number words / 3 pts

three is \( 3 \) (1 pt). seven is \( 7 \) (1 pt). zero is \( 0 \) (1 pt).

3 Count out nine / 4 pts

(a) He says nine (1 pt).

(b) The numeral is \( 9 \) (1 pt).

(c) Zoe skipped the word four, so her last number, ten, is wrong (1 pt). She touched each of the nine pencils once, so the cup holds \( 9 \) pencils (1 pt).

4 Circle and array / 4 pts

Circle: start at the ring and go around: one, two, three, four, five, six, seven. There are \( 7 \) counters (2 pts).

Array: two rows of eight. Count the first row to eight, keep going in the second row, nine to sixteen. There are \( 16 \) squares (2 pts).

5 Counting on to twenty / 3 pts

The missing numbers are seventeen and nineteen: \( 17 \) and \( 19 \) (2 pts). The number right after twelve is \( 13 \) (1 pt).

6 Think about it / 2 pts

She has the same number of cubes, \( 6 \) (1 pt). Moving objects does not add any or take any away, so counting again gives six (1 pt).
