### Teaching and Group Activities for Understanding

**Day 1**Children use digits 1 to 7 to make whole numbers between 3 million and 4 million.

*Hold up your number if it has 2 in the 100,000s place… if it has 2 in the 10,000s place… if it rounds to 3,000,000.*Ask a few children to place their numbers on a 3,000,000 to 4,000,000 line. End by creating today’s ‘Top Tip for Tests’.

**Group activities**

-- Complete rounding and place value problems.

**Day 2**Show children the 6 function machines.

*If I want to convert 3.45m into centimetres, which function machine could I use?*A point for each correct team. Repeat for converting 56cm to metres, 3.487 kg to grams, 480g to kg, etc. End by creating today’s ‘Top Tip for Tests’.

**Group activities**

-- Practise multiplying numbers by 10 and 100.

-- Multiplying and dividing by 10, 100 and 1000, including converting units of measurement.

**Day 3**Sketch a line from -20 to 20, mark on -20, 0 and 20. Ask children to label -7, -11, 4 and 12.

*Which is more -7 or -11? Which is closer to 0? If these were temperatures, which would be cooler? What is the difference between -7 and 4?*Sketch a -100 to 100 line, label -100, 0 and 100. Children mark on given multiples of 10. End by creating today’s ‘Top Tip for Tests’.

**Group activities**

-- Sketch number lines to help solve word problems using positive and negative numbers.

-- Find the difference between pairs of 2-digit numbers, 1 of them negative.
