Hamilton Objectives
2. Estimate quantities and represent numbers in different ways.
5. Solve number problems and practical problems involving place value.
32. Use both £ and p in practical contexts.

### Planning and Activities

Day 1 Teaching
Use mock or Interactive Whiteboard coins to show £2.40 and £2.04. Explain that the zero in £2.40 shows that are no pennies, and the zero in £2.04 shows that there are no 10ps. Which is more money, £2.04 or £2.40? Model adding and subtracting amounts of money. Play the ‘Nasty Game’ to make the smallest and largest amounts of money.
Group Activities
-- Play the ‘Nasty Game’, making 3-digit numbers with money.
-- Solve and create word problems for addition and subtraction with 3-digit amounts of money.

Day 2 Teaching
Show pictures of priced toys (see resources). Children work out how much it would cost to buy 10 whistles at 34p each. Model writing 34p in a money place value grid and moving the digits to the left to multiply by 10. Repeat for other toys.
Group Activities

Group Activities
-- Make 3-digit numbers to place on a 1–1000 number line.
-- Identify 3-digit numbers that are higher, lower or in-between other numbers on a 1–1000 number line.

Day 3 Teaching
Two children hold number cards 600 and 700 at either end of the room. A third child stands where 684 might be on an imaginary line from 600 and 700, keeping the number secret. Children discuss in groups what the number might be. Round the number to nearest 10. Repeat.
Group Activities
Use the in-depth problem-solving investigation ‘Guess my number’ as today’s group activity.
