# Maths Reception Spring Addition and Subtraction

Each week-long unit has everything you need to teach a set of related skills and concepts. ‘Maths Out Loud’ provides essential whole-class practice of counting and repetitive chants, rhymes and songs, along with a linked story to enjoy together.

The three remaining sections provide a choice of activities to target the key characteristics of effective early learning. Through ‘Exploring and Playing’, children will engage with their peers and their environment. ‘Active Learning’ should promote the motivation needed to be involved and to keep trying. Many of the activities suggested in ‘Creating and Thinking Critically’ support early development of children’s problem-solving and reasoning skills.

‘UNIT PLAN’ gives you a text version of all parts of the unit to use in your school planning documentation. ‘DOWNLOAD ALL FILES’ gives you that unit plan plus all of the associated documents. The downloads in each section of the first unit are free to download for all users. However these bulk downloads are only available to Hamilton Friends and School Subscribers, representing added value for those users.

## Unit 1 Say the number 1 more/ less (suggested as 5 days)

### Objectives

Say the number 1 more/ less

Unit 1: ID# R509

Development Matters

Counts objects to 10, and beginning to count beyond 10.
Says the number that is one more than a given number.
Finds one more or one less from a group of up to five objects, then ten objects.
In practical activities and discussion, is beginning to use the vocabulary involved in adding and subtracting.
Records, using marks that they can interpret and explain.
Counts reliably with numbers from one to 20, places them in order and says which number is one more or one less than a given number.
Using quantities and objects, adds and subtracts two single-digit numbers and counts on or back to find the answer.

Early Learning Goals

Say which number is one more or one less than a given number.

Hamilton Objectives

11. Find one more than a group of up to 5 objects and then up to 10 objects.
14. ELG: Say the number one more than a given number up to 20.
15. ELG: Say the number one less than a given number up to 20.

### You Will Need

Exploring and Playing

A complete set of dominoes; chairs; a steering wheel and a bus stop; items in a class shop; price labels; pens; playground chalk; bean bags.

Active Learning

A tin or money box; 12 pennies; 12 soft toys, a blanket; 10 chairs; covered car park (see preparation); 10 cars.

### Maths Out Loud

Counting

Shuffle a set of 1-10 cards. Show one. Children say the next number, then carry on counting until you say stop. Repeat with other cards.
On a different day, repeat, but this time, children count back to zero.
Use number shapes – such as Numicon - for the same activity, asking Which shape is 1 more/ 1 less than this one?
Analyse and visualise number images, e.g. by showing children the dice pattern for 5 and asking them What numbers can you see hidden inside this number?

Chants/Rhymes/Songs

Sing a song or say a rhyme which starts with one object/character and adds one more each time, e.g. One elephant went out to play, or One man went to mow, such as this animated version of One Man Went to Mow on YouTube.com.
