Chapter 5 of Class 1 Joyful Mathematics, How Many?, builds on counting to gently introduce addition and subtraction using real-life objects.
Key Concepts
Addition: combining two groups and counting the total, e.g. 3 + 2 = 5.
Subtraction: taking some objects away and counting what remains.
Number sentences: reading and completing simple sentences like 3 + 2 = ___, using fingers, beads, or toys to work it out.
Quick Recap
- To add, physically combine both groups first, then count the whole set once.
- To subtract, count the starting group, remove the stated number, then count what’s left.
Common Mistake to Avoid
Recounting from 1 every time instead of counting on — for 3 + 2, encourage counting on from 3 (“4, 5”) rather than restarting from 1.
Frequently Asked Questions
What household objects work well for practising addition and subtraction?
Small, safe objects like buttons, coins, or toy blocks that can be physically grouped, combined, and removed.
Why use real objects instead of jumping straight to numbers?
Physically combining or removing objects makes the meaning of addition and subtraction concrete before the child works only with symbols.
