### Teaching and Group Activities for Understanding

**Day 1 Teaching**

Write the number sentence 3 + ☐ = 8. Children discuss. Did they count on or use their fingers? Hold up a strip of 8 cubes and beneath it a strip of 3 cubes. How many more cubes to make 8? Fill in the number sentence 3 + 5 = 8. Repeat for other bonds to 8. Record the bonds to 8. Choose an addition; cover one number, ask children to find it.**Group Activities**

-- Find the matching number to make 8.

-- Order number bonds to 8; find matching number bond partners.

**Day 2 Teaching**

Write 9 + 0, 3 + 6, 7 + 2, 4 + 5, 8 + 1 and show that these are all bonds to 9. Can we write them differently? Show that we can write addition either way round. 3 + 6 = 9 and 6 + 3 = 9. Rehearse using these bonds to write subtraction facts, e.g. 9 – 4 = 5.

**Group Activities**

-- Making number bonds to 9 with cubes in a feely bag.

-- Play a game creating number bond number sentences with a partner.

**Day 3 Teaching**

What is double 3? Explain that when we double a number we actually add it to itself, e.g. 4+4, 6+6 etc. Ask children to work in pairs to show doubles to 6 on their fingers.

Draw a 3 by 2 grid on IWB. Fill with numbers 1 to 6. Children copy and write doubles.**Group Activities**

Use the investigation suggestions in ‘Double Trouble’ from NRICH for today’s group activity.

Or, use these activities:

-- Fish for doubles, collecting as many fish as they can.

-- Quick-fire game of doubles and halves.
