Mental Addition – ObjectivesWork out, very quickly, pairs with a total of 100; Add pairs of 2-digit numbers. You will need: 1-9 digit cards (one set per two students) © Hamilton Trust Keeping Up Term Week 2 Day 1
Mental Addition – Direct Teaching=33 Handy Hint Look for the bond to 10 for the ones digit and the bond to 9 for the tens digit… +3 +30 How many more to make 100? © Hamilton Trust Keeping Up Term Week 2 Day 1
Mental Addition – Student ActivityWith a partner, shuffle a pack of 1 to 9 digit cards. Take it in turns to take the top 2 and use them to make a 2-digit number. Work out what is needed to make 100. 2 4 Watch out for students who think that 47 needs to be added to 63 to make 100 for example, because they look for tens which add to 100, not 90. Also watch out for students do not have instant recall of number facts for addition of single-digit numbers. 3 5 7 6 8 9 1 © Hamilton Trust Keeping Up Term Week 2 Day 1
Mental Addition – Direct TeachingWhat strategies could you use to solve these calculations? Ask students to discuss in pairs how they might solve the additions shown. © Hamilton Trust Keeping Up Term Week 2 Day 1
Mental Addition – Direct Teaching Partitioning and Recombining Add the 10s 110 Add the 1s 7 + 8 15 Partition Take students’ suggestions, then model this strategy. 125 Recombine = © Hamilton Trust Keeping Up Term Week 2 Day 1

2 4 3 7 9 6 5 8 Mental Addition – Individual Practice orCreate pairs of 2-digit numbers using: 2 4 3 7 or 9 6 5 8 The blue box is slightly trickier, as it will result in more pairs where the ones digit totals more than 10. Take feedback on the biggest and smallest possible answers. Watch out for students who: • do not have instant recall of number facts for addition of single-digit numbers; • have difficulty when the addition means passing through the next multiple of 100, e.g ; give more practice counting in 10s through multiples of 100. Add the pairs together. How many different totals can you make? © Hamilton Trust Keeping Up Term Week 2 Day 1
