Vertical addition to 20, no regrouping
- Age
- Ages 6–7
First choose what to practice: representing quantities, calculating or solving a word problem.
Addition combines quantities or adds one quantity to another. For 8 + 5, make 10 first: split 5 into 2 and 3, calculate 8 + 2 = 10, then add the remaining 3 to get 13.
Read what happens and what is being asked before choosing an operation. “There are 8 pencils and 5 more arrive” gives 8 + 5; “there are 8 pencils and 5 are given away” gives 8 − 5.
Count 7 objects, add 2 and represent 7 + 2 = 9. Then remove 2 to return to 7.
Draw 5 rows of 4 dots: 5 × 4 = 20. Use the same array to explain 20 ÷ 5 = 4.
Use theme motifs as objects in a word problem. Three groups of four ornaments total 12; removing two leaves 10.
First choose what to practice: representing quantities, calculating or solving a word problem. A learner may be confident with addition but need drawings to understand division. Grade labels help you browse; the skills required by each exercise help you choose.
Work through one example aloud before independent practice. To check 18 + 7 = 25, calculate 25 − 7. If a word problem asks about meters or coins, include that unit and check whether the answer fits the situation.
