M2i. Can add two 2-digit numbers using concrete objects or pictorial representations = teacher notes

Teacher Information This resource should be used to support Key Marginal pupils for whom you have completed a PLC. It is designed to be delivered as a teaching activity to a small group or individual in order to fill a gap in their understanding. There is no expectation to use the PowerPoint in its entirety. Choose the methods and resources that suit your school’s approach to place value, counting and calculation. Use of this resource should form part of normal, day-to-day teaching, as you would do with a guided teaching group. This teaching resource is based on the National Curriculum expectations for Key Stage 1, with a focus on the laser-sharp statements from the PiXL PLC.

LORIC Our Primary Edge attributes help us to become better learners and today is no exception. Before you start this activity, here are some ideas for how you will need your Raj Resilience skills today: Command Words: Persevere Complete Overcome Achieve Sustain Undertake Learn over time Trying hard even when it is challenging. Learning from your mistakes. Asking for help if you need it.

Developing Resilience Skills Use this activity to help children develop their resilience skills before you begin the therapy. Have a small group of children stand in a circle and ask them to pass a hula-hoop around the circle. Discuss whether this was easy or hard. Then ask the children to stand in a circle whilst holding hands with one another. However, before the last pair connect hands place the hula-hoop over one arm. They need to now pass the hula-hoop around the circle without letting each others’ hands go. After a few attempts ask the children what made it difficult and discuss the ideas they came up with to solve any challenges. Did you try hard even when the challenge got a little trickier?

What I Will Be Looking For Today You will have lots of chances to demonstrate your resilience skills today. Here’s what I’ll be looking for: Learn from your mistakes. Trying hard even when it is challenging. Asking for help if you need it.

Teacher Information For this therapy children will need to have access to a range of practical maths equipment such as Numicon, number lines, base ten apparatus and 100 squares to assist them with their addition.

Using Counters to Add Two 2-Digit Numbers Counters or blocks, in fact any objects, can help us to add two 2-digit numbers. However, choose this resource when the numbers are not very large. Counting out large numbers takes a lot of time and may lead to errors. Counting is easier when you arrange the counters in rows. 14 + 11 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 = 25 21 22 23 24 25 Check your answer

Adding Two 2-Digit Numbers Using Tens Frames Another option if the 2-digit numbers are not too large is to use a tens frame. 15 + 18 =? How many counters have you got altogether? 15 + 18 = 33

Using Numicon to Add Two 2-Digit Numbers Can you find the total of 28 + 14? We can add the tens first. 28 + 14 = + Now we can add the ones. 20 + 10 = 30 8 + 4 = 12 You could have split the 4 into 2 and 2 to make the final addition easier. 30 + 12 = 42

Practise Your turn. Use Numicon to solve 37 +23. 37 + 23 = + We can add the tens first. Now we can add the ones. 30 + 20 = 50 7 + 3 = 10 50 + 10 = 60

Using Base Ten Apparatus to Add Two 2-Digit Numbers Keep organised by using a tens and ones frame. 67 Tens Ones 43 + 24 = Add the ones first 3 + 4 = 7 Add the tens next 40 + 20 = 60 Add the two answers together 60 + 7 = 67

Practise Your turn. Use base ten apparatus to find the sum of 52 + 34. Tens Ones 86 52 + 34 = Add the ones first 2 + 4 = 6 Add the tens next 50 + 30 = 80 Add the two answers together 80 + 6 = 86

Teacher Information Number lines and a 100 square can be abstract and confusing for young children. Ensure children are confident using other concrete resources before moving onto either of these. Only extend to a number line or 100 square if appropriate.

Using a 100 Square to Add Two 2-Digit Numbers As the 100 square is in rows of ten, we can add on tens by jumping down a row for each ten. 93 73 + 20 = We jumped down two rows as 20 has 2 tens.

Using a 100 Square to Add Two 2-Digit Numbers For each unit we move forward one square. 52 + 21 = ? 73 52 + 21 = We jumped down two rows as 20 has 2 tens and moved forward 1 square for the ones.

Practise 69 Find the total of 27 + 42. 27 + 42 = Did you jump down 4 rows for each ten in 40 and move forward 2 squares for the ones in 42?

Using A Number Line to Add Two 2-Digit Numbers Find the total of 53 + 29. Add 20 to 53 first. Now add 9 ones to 73. 53 + 20 = 73 53 + 29 = 82

Use a number line to solve 64 + 32. Practise Use a number line to solve 64 + 32. Add 30 to 64 first. Now add 2 ones to 94 64 + 30 = 94 64 + 32 = 96

Choose your favourite method to find the answers to these additions. Practise Choose your favourite method to find the answers to these additions. 33 + 27 = 60 28 24 52 47 36 83 55 43 98 64 18 82 72 21 93 81 25 106 95 32 127

Teacher Information Show Me Tasks Once the therapy has been delivered you can use Show Me Tasks to demonstrate that the skill is now secure. They are not intended to be completed all at once and ideally should be done in intervals of a few days after the therapy has been delivered. The challenge in the tasks is progressive. For these tasks please ensure children have access to a range of practical maths equipment to allow them to select the resources they need.
