Maths – Y1

Number and Place Value

In Year 1 children focus on reinforcing their understanding and use of 2 digit numbers. Initially they will focus on numbers to 20, once secure they will extend to numbers within 50 and during the summer will extend to numbers within 100. They should be able to read any 2 digit number and partition into tens and ones. Children in Year 1 focus on explaining what they know about numbers verbally or using pictures and representations. They can compare and order numbers with confidence.

Key Vocabulary
tens	ones	less than	greater than

Addition and Subtraction

Children in Year 1 will focus on learning to recall and use their number bonds of 10 and related subtraction facts within 20.

Children will add and subtract one-digit and two-digit numbers to 20, including zero.

They will solve one-step problems that involve addition and subtraction, using concrete objects and pictorial representations, and missing number problems such as 7 = ¨ – 9.

Strategies for addition	Example
Number stories	First there are 5 ducks in the pond.. Then 2 more ducks swim along. Now there are 7 ducks in the pond. First Then Now 5 + 2 = 7
Adding with concrete objects and then pictures	The children would physically have the 10s frame and the counters before using pictures. This shows 5 +2 = 7 The counters on the 10s frame to represent and link back to number stories.
Empty number line	The children will draw the number line and write their starting number (as they are adding they will start on the left and jump forwards). They will need to make sure they draw the jumps, what the jumps represent and the numbers.
Using known facts (including number bonds to 10 and doubles)	The children should be able to recall their number bonds to 10 and doubles (for numbers under 10) by the end of year 1.
