Level 2 ADDITION AND SUBTRACTION

I am learning to solve Level 2 addition and subtractions using place value.

 1. There are 21 people at a beach, and 13 more people arrive. Show how to work out how many people are at the beach altogether.

21+13=? 20+10=30 30+10=40 and you add the 30 and the 4 together that makes 34 2 and 1 are not just ones. They are 10s. 2 tens and 1 tens = 3 tens.

 2 Two classes go on camp together. One class has 47 students and the other has 38. Show how to work out how many students go on camp

47 + 38 ? ✔ 40 + 30 = 70 ✔ 7 + 8 = 15 ✔ 15 + 70 = 85 ✔ This is good. you showed you understand using place value.

 3. A farmer has 63 cows. He buys 39 more cows. Show how to work out how many cows he has altogether.

63 + 39 ? 60 + 30 = 90 3 + 9 =12 12 + 90 =102 ✔ Great! We need to practise a lot more activities like this. POST
