### Planning and Activities

**Day 1**

Sort additions into 2 groups: those we prefer to calculate by counting on, and those where children would choose place value/number facts.

**Further Teaching with Y1**

Use the bead bar to show bridging 10 when adding 1-digit numbers.

**Group Activities: T with Y1**

Y1 -- Add two 1-digit numbers by bridging 10, using either a bead string or beaded line.

Y2 -- Sort and solve additions according to how they might best be solved (counting on, place value or number facts).

**Day 2**

Add 1--digit numbers of pennies, bridging 10p on a money line.

**Further Teaching with Y2**

Add 9 to 2-digit numbers by adding 10 then subtracting 1 on a 1 to 100 grid.

**Group Activities: T with Y2**

Y1 -- Use penny lines to help solve money additions, adding 1–6p or 1–10p.

Y2 -- Repeatedly add 9 on a 1 to 100 grid, starting at 19, and describe the pattern. Some children will work in pairs to add 10, then 9 to 2-digit numbers.

**Day 3**

Imagine the colours of beads when bridging 10 to find 8 + 3, for example. Discuss which additions bridge 10 and which don’t.

**Further Teaching with Y2**

Use place value cards then 10p and 1p coins to add pairs of 2-digit numbers (1s less than 10).

**Group Activities: T with Y2**

Y1 -- Use bead strings to add 5 and 6 to 6, 7, 8 and 9, discussing how the 5 and 6 are split each time. Record bridging 10 on a landmarked line.

Y2 -- Use 10p and 1p coins, or place value cards, to add 2-digit numbers.

**Day 4**

Use place value cards to add pairs of 2-digit numbers (1s greater than 10). Y1s use bridging to add the 1s.

**Further Teaching with Y1**

Use 1-digit + 1-digit facts to find 2-digit + 1-digit answers, such as using the answer to 4 + 3 to calculate 14 + 3, 24 + 3.** Group Activities: T with Y1**

*Use the in-depth problem-solving investigation ‘Domino additions’ as today’s group activity.*

Or, use these activities:

Y1 – Refer to addition cards, or recall 1-digit + 1-digit addition facts; use these to find the answers to 2-digit + 1-digit calculations.

Y2 -- Use place value cards to add two 2-digit numbers, discuss if the 1s will make an extra 10 or not. Some children will sort additions into those with answers less/more than 80, because the 1s digits total more than 10.

**Day 5**

Calculate 5 + 4, 15 + 4, 25 + 4 … 95 + 4 on the 1–100 grid, discussing the pattern.

**Further Teaching with Y2**

Add 19 on a 1–100 grid by adding 20, then subtracting 1.** Group Activities:**

Y1 -- Use dominoes to generate 2-digit plus 1-digit number additions in a pattern. Some children may answer addition number sentences, recognising and using known facts.

Y2 -- Add 19 on the 1–100 grid, by adding 20, then subtracting 1. Some children may add ‘nearly’ numbers using a calculator, look for patterns, predict answers
