In class we have been using Time Loop cards:
I have half past 3. Who has one hour later?
I have half past 4. Who has 2 hours earlier?
Loop cards help us think quickly so we can get back to the start again. They are fun.
We can use Topmarks Loop cards online to speed up our adding, subtracting, multiplying and doubling. Maybe you want to try some in the holidays. Have fun!Topmarks Loop cards
