Add parts to find the value of the whole and write the equation

Maths

In this unit pupils will combine 2 or more parts to make a whole. They will learn addends are represented in any order and the = sign shows the whole and sum of the parts are equal. In the future unit pupils will find missing addends. They will partition a whole into 2 parts representing first, then, now stories with subtraction equations. They will learn + and - are inverse operations.

In prior learning, pupils will have learnt to count confidently and have developed a deep understanding of the numbers to 10, the relationships between them and the patterns within those numbers. In this unit pupils will combine two parts to make a whole, learn that addends are represented in any order and learn that the equals sign shows that the whole and the sum of the parts are equal.

Write an equation to represent the part-part-whole model and solve it. Do not use spaces.

There are 3 pebbles in one box and no pebbles in the other box. Which equation would I write to find out how many pebbles there are altogether? Do not use spaces.

Which equation can be used to represent this picture?

Izzy has 3 counters and Jun has 5 counters. They combined the parts to find out how many altogether. Which equation could represent this?

Which equation represents this part-part-whole model?

I have 8 pencils altogether. 6 are red and 2 are yellow. Which equations would represent this?

There are 3 bananas and 4 apples. There are 7 pieces of fruit altogether

There are 4 pieces of fruit altogether. 3 of those pieces are apples.

Which story could these counters represent?

Jun has written three equations to match this picture. Which other equation could he write? Do not use a space.
