Year Two Maths For today’s Maths lesson, you will focussing on addition
Warm-up Write down as many facts about the number 48 as you can Example: 48 is an even number
Addition Using a number line, solve this number sentence 17 + 26 =
Addition Using a number line, solve this number sentence 17 + 26 = That’s right, you start at 17 and add 2 tens and then 6 ones +10 17 +10 27 +1 38 39 +1 +1 40 +1 41 +1 42 43
Addition Using partitioning, solve this number sentence 44 + 39 =
Addition Using partitioning, solve this number sentence 44 + 39 = 83 40 + 4 + 30 + 9 = 70 + 13 = 83
Addition Challenge yourself! Using column partitioning, solve this number sentence. Start by writing the number sentence vertically (from top to bottom) 39 + 48 = And then partition it 39 +48 Add the tens together and write the total underneath the tens column Add the ones together and write the total underneath the ones column Add your tens and ones together and write the total underneath the column with the original number sentence
Addition Check your answer Start by writing the number sentence vertically (from top to bottom) 39 + 48 = 87 And then partition it 39 +48 + 39 30 + 9 48 40 + 8 87 70 + 17 Add the tens together and write the total underneath the tens column Add the ones together and write the total underneath the ones column Add your tens and ones together and write the total underneath the column with the original number sentence
Addition Level 1 Level 2 Level 3 Challenge Solve these number sentences using a number line 25 + 20 = 26 + 20 = 25 + 23 = 23 + 27 = 21 + 28 = 24 + 25 = 12 + 32 = 22 + 23 = 15 + 21 = 23 + 24 = Solve these number sentences using partitioning 37 + 22 = 35 + 35 = 19 + 44 = 28 + 51 = 17 + 66 = 29 + 37 = 36 + 42 = 71 + 23 = 64 + 28 = 69 + 37 = Solve these number sentences using the new column partitioning Marwa went to the shop she bought 2 tine of soup that were 64 p each. Write your answer and explain what you used to help you work it out. 47 + 32 = 37 + 45 = 39 + 54 = 49 + 46 = 18 + 46 = 29 + 67 = 48 + 59 = 82 + 39 = 69 + 84 = 58 + 68 = visualisation. Think of a pot that has 74 p in it. Add 10 p, 10 p and 5 p How much is in the pot now?
