Today we will be following on from yesterdays lesson, finding the difference between two numbers.
Task one: count up to work out a small difference between two numbers
We can find the difference between two numbers by counting up on a number line or bead string, jumping to the next multiple of ten. This uses our known number knowledge.
Look at Task One photo. 42 - 36 = ?
Now have a go at answering the questions next to it.
Task 2: Work out change from 50p and £1 for items priced between 30p and 50p
Using the printable cards or by creating some of your own. Pick a picture card and write a number sentence to work out the change from 50p or £1 (Remember £1 is the same as 100p)
The hot dog picture is 38p. 50p - 38p = 12p
Draw yourself a number line to help work out the answer see Task 2 picture.
Task three: Look at these questions. Are they true or false? Do I need to do more than one operation to answer the question? This means I may have to add up before I take away. This is called a two step problem.
