# Thursday 7th January

Warm up:
(Choose between:)
- counting in 2’s / 5’s /10’s /4’s / 8’s
- counting backwards from a chosen number between 0 and 100

This first half of today’s lesson is recapping what we did yesterday. Partitioning the first 2 digit into tens and ones, circling the ones with the remaining 1 digit number and adding them together. It is important that children understand this method so that they have a bank of ways of working something out if they feel challenged. Here are some examples to keep up practise.

Please encourage the children to write the number sentences out themselves this time and follow the procedure step by step to find the answer. They can do the calculation in their heads to double check.

46 + 3 =                   28 – 2 =

21 + 8 =                   19 – 4 =

50 + 6 =                   36 – 5 =
34 + 3 =                   47 – 5 =

If they are okay with that and can do these examples confidently and independently then move onto the extension task.

Extension:

Talk to your child about column method. Can they remember this from before Christmas?
How would I work out

34 + 12 = ?

See if they can tell you or show you these steps:
1. Stack the numbers (make sure they line up properly)
2. Always add the ones first

If the children don’t remember then you might have to remind them and talk them through the steps again.
Can the children complete these number sentences using the column method:
12 + 11 =
30 + 20 =

45 + 44 =

51 + 21 =
16 + 33 =

18 + 81 =
