Altogether and left
Name Date
Ask a grown-up to read each question to you. Use a pencil.
Exercise 1: Count the pictures and add. Write how many altogether.
Exercise 2: Some are crossed out. Write how many are left.
Exercise 3: Circle every sum that makes 6.
Exercise 4: Fill in the missing number so that each sum makes 7.
6 + = 7, 5 + = 7, 4 + = 7
Exercise 5: Join each sum to its answer.
Exercise 6: Count back. Fill in the missing numbers.
10, 9, , 7, 6, , 4, 3, , 1, 0
Exercise 7: Add or take away. Write the answer under the line.
5+59−41+37−0Exercise 8: Box A: draw 4 shells, then draw 2 more. How many altogether? Box B: draw 6 shells, then cross out 2. How many are left?
ABExercise 9: Trace 0. Zero means none are left.
Answer key for grown-ups
How Many? · Class 1 · Joyful Mathematics · Chapter 5. Check together and praise the effort, not only the answer.
- 1Count the pictures and add. Write how many altogether.2 + 2 = 4, 1 + 5 = 6, 6 + 1 = 7
- 2Some are crossed out. Write how many are left.5 − 2 = 3, 7 − 1 = 6, 8 − 4 = 4
- 3Circle every sum that makes 6.Circle cards 1, 3 and 5.
- 4Fill in the missing number so that each sum makes 7.6 + 1 = 7, 5 + 2 = 7, 4 + 3 = 7
- 5Join each sum to its answer.1 → A, 2 → C, 3 → B, 4 → D
- 6Count back. Fill in the missing numbers.10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0
- 7Add or take away. Write the answer under the line.5 + 5 = 10, 9 − 4 = 5, 1 + 3 = 4, 7 − 0 = 7
- 8Box A: draw 4 shells, then draw 2 more. How many altogether? Box B: draw 6 shells, then cross out 2. How many are left?Box A: 4 shells and 2 more, 6 shells altogether. Box B: 6 shells with 2 crossed out, 4 shells left.
- 9Trace 0. Zero means none are left.Check that the tracing follows the dots.
What your child practised
- Putting two groups together and saying how many altogether, then writing it as a sum: 2 and 4 make 6, so 2 + 4 = 6.
- Counting on from a number, with fingers, dice, beads or hops along a number path, and seeing that adding 0 changes nothing.
- Taking away and saying how many are left, counting back, and finding how many are hiding when some are covered.
