Maths Year 2 Spring Addition and Subtraction (B)

Each unit has everything you need to teach a set of related skills and concepts.

Find money totals: solve word problems (suggested as 3 days)

Planning and Activities

Day 1 Teaching
Use BBC website to play a game of ‘Igloo shopping’. Children have a pot of money and choose coins to pay for different objects. Check on screen. Move to the hard level to select and pay amounts like £4.23.
Group Activities
Use the ‘Coin Trios’ in-depth problem-solving investigation below as today’s group activity.
Or, use these activities:
-- Play an online shopping game to make given amounts, offering alternative combinations.
-- Use coins to make given amounts, offering alternative combinations.

Day 2 Teaching
Set up a shop with priced items. Children select two items and work out the total using a familiar strategy based on adding 10ps and then the 1ps to the larger starting number. Repeat. Make errors in your addition as the teacher and have children correct you, modelling the method.
Group Activities
-- Shop for two items with 2-digit prices, adding to find the total.
-- Play Cuddly Toy Sale game online, adding two 2-digit amounts.

Day 3 Teaching
Display a Word problem. Discuss the strategies that might be needed to solve it. Take suggestions. Write a number sentence to represent the problem. Children display a subtraction or addition symbol in response to your reading more word problems to show which operation they would use to solve them.
Group Activities
-- Sort and solve addition and subtraction word problems.
-- Create addition and subtraction word problems.

    Suggest these three ways. One way uses 5 coins. Can you find it?
