• Read and write numerals from 0 to at least 20.
• Begin to know what each digit in a two-digit number represents. Partition a 'teens' number and begin to partition larger two-digit numbers into a multiple of 10 and ones (TU).
• Understand and use the vocabulary of comparing and ordering numbers, including ordinal numbers to at least 20. Use the = sign to represent equality. Compare two familiar numbers, say which is more or less, and give a number which lies between them.
• Within the range 0 to 30, say the number that is 1 or 10 more or less than any given number.
• Order numbers to at least 20, and position them on a number track.

Writing Numbers: KS1 Level 1

Aims: Reinforce recognition of numerals and their value. Strengthen association between number concepts and real-life. Encourage formation of numerals using motor-skills.

Extension: Use numbers larger than 10. Encourage children to draw their own numbers.

Number Ladders: KS1 Level 1

Aims: Introduce the concept of adding up to 5 more or taking away up to 5 less. Use a ladder to illustrate the concept.

Extension: Look for and explain patterns in the numbers. Try adding or taking away another amount. Use two-digit numbers for a greater challenge.

Number Sequences: KS1 Level 1

'Cut and Match'
Aims: To make links between numbers, words and pictures from 0 to 9.

Extension: Continue further up the number scale toward two-digit numbers. Children could only be given a number, word or picture and then have to draw the other two.

'Stand in Line'
Aims: Rehearse knowledge of a number line from 0 to 10. Children add missing numbers in the right places.

Extension: Use a moveable number line to muddle up more numbers for children to put back in the correct places. Extend the number line to 20 for a greater challenge. Reinforce by getting children to wear numbers and physically stand in a line in the right order.

'Don Fandango's Treasure'
Aims: Reinforce knowledge of numbers up to 20. Children add the missing numbers to the sheet.

Extension: Attempt the sheet 'backwards'. Start at 20 and count backwards filling in the gaps. Identify the even and odd numbers by making them different colours.

'Alien Footprints'
Aims: Reinforce knowledge of numbers up to 15. Children add the missing numbers to the sheet.

Extension: Attempt the sheet 'backwards'. Start at 15 and count backwards filling in the gaps. Identify the even and odd numbers by making them different colours.

'House Numbers'
Aims: Consolidate the number line from 1 to 9, identify and add the missing numbers. Put the number line together in the right order.

Extension: Make the street of houses longer (up to 20); reverse the order of the houses to start at the biggest number.

Making Numbers: KS1 Level 1

'Making 10'
Aims: Practise number bonds to 10 with addition. Children match the correct pairs together.

Extension: Reverse the number bonds to rehearse number bonds with taking away eg: 10 - 4 = 6. Use number bonds up to 20.

'Tanto's hiding place'
Aims: Children add three to numbers up to 20 to find their way to the 'hiding place'.

Extension: Ask children to talk about the patterns they can see in the solutions. Children attempt the activity without using the number line.

'Football Shirts'
Aims: Introduce the concept of missing numbers and practise solving a variety of adding and taking away sums.

Extension: Remove the number line and ask more able children to demonstrate how they solve the problems.

Number Puzzles 1 - 10
Aims: Develop ability to solve missing number sums up to 10 or 20 and rehearse knowledge of number bonds.

Extension: Set a time limit and see how many the children can do in a minute.

Number Stories: KS1 Level 2

Aims: All the sheets use everyday examples to reinforce the concepts of:

• Birthday cakes (take away 2)
• Balloons (take away 5)
• Ice Creams (take away 4)
• Sweets (adding 2)
• Apples (adding 4)

Extension: Try the same sums without the visual or physical aids.

• Difference of 9 or 10
• What's the number?

Begin to understand the word 'difference' and become accustomed to seeing numbers written in different styles.
