Learning Objective
|
Clip to support understanding
|
- Know number bonds to 10 and 20
|
|
- add mentally a series of one-digit numbers
|
|
- add multiples of 10 (such as 60 + 70) or of 100 (such as 600 + 700) using the related addition fact, 6 + 7, and their knowledge of place value;
|
|
- partition numbers using place value counters (this enables the pupil to see and understand the value of the numbers they are working with)
|
|
- Children are taught to say numbers in familiar contexts such as number rhymes or in role-play. This will develop into the counting of everyday objects.
|
|
- Children will learn to sort and classify before moving on to adding.
|
|
- The children will be taught to say and write the numbers in a range of ways (e.g. in sand, with a pencil, with chalk) to match up names and quantities and order them.
|
|
- Children will be taught to solve problems involving the use of the skills listed above.
|
|
- The children will be taught to use the vocabulary involved in addition through practical activities and discussion e.g. more, and, add, sum of, total, altogether.

|
- Children will use a range of equipment such as objects, ten frames, Numicon and everyday objects to learn to count and add up.
- By using visuals in ten frames or with Numicon children will start by counting each visual but after a while they will just know what 10 looks like, what 6 looks like and so on.
- Children also develop their ‘number sense’ by learning to group in different ways.

|
- Children are encouraged to use a number square to add by counting on, initially in units, then in tens and units. This is a useful visual aid for children should they need it.

|
- Alongside adding with a 100 square,the number line can be used as another visual reference.

|
- The children are also encouraged to use their fingers to count in the early stages
|
|
- Children then begin to use numbered lines to support their own calculations using a numbered line. For example, adding a two digit number to a two digit number.

|
- The next step is to use an empty number line

|
- Learning to partition in different ways helps children to understand what they are adding
