We’re very excited as all three of their teams have reached the semi-finals of the Rugby World Cup. Not only was this a chance to wear their shirts, it also meant we could work on some addition.

## Resources

• Grimm’s rings and boards
• Numicon
• Team flags
• Numbered log slices

## Method

Ioan was keen to explain the ‘part-part-whole’ method to Finn. It can demonstrate the relationship between a number (whole) and it’s components (parts). We used this morning’s match between England and New Zealand to demonstrate.

England scored the first try (5 points) and converted it for an extra 2 points.

Ioan put a Numicon number 5 in the hoop on one side and a two in the hoop on the other. These were the two ‘parts’. To find the ‘whole’ he added a five and two together to make a 7, which went in the circle at the bottom. He then updated the scoreboard at the top.

Next, England scored a penalty. He added their 7 points to the 3 points for a penalty so he updated the score by adding a 7 and a 3 to get 10. The score was now England 10:0 New Zealand.

New Zealand scored a converted try, making the score 10:7.

When England scored another penalty, they worked out 10+3.

England’s third penalty, made the score 16:7.

Three excited boys.

## DfES Early Learning Goals (2017)

### Mathematics

#### ELG 11 – Numbers:

Children count reliably with numbers from 1 to 20, place them in order and say which number is one more or one less than a given number. Using quantities and objects, they add two single-digit numbers and count on to find the answer.

## DfES Outcomes for EYFS and National Curriculum (2013)

### Mathematics Year 1 programme of study

#### Number – addition and subtraction

• read, write and interpret mathematical statements involving addition (+), subtraction (–) and equals (=) signs
• represent and use number bonds and related subtraction facts within 20
• add and subtract one-digit and two-digit numbers to 20, including zero
• solve one-step problems that involve addition and subtraction, using concrete objects and pictorial representations.
