This week we will be subtracting (taking away) objects. First practise writing all your numbers up to 20 by making your own number cards. Cut them out, mix them up and use them for this subtraction activity:
Turn over a number card. Find that number of objects (you could have a hunt in the garden and collect leaves / twigs / stones to use). Then roll a dice and take that number away. Are you left with more or less?
Extension: Can you write what you have done as a number sentence?
(Watch out! Sometimes you may not have enough objects to be able to take away! E.g. If my starting number card is 4 and I roll a 6, I cannot take 6 away from only 4.)
Practise crossing out pictures to find the answer to these subtraction questions in the activity sheet below.
This week we will be learning about doubles. Double is when we have 2 groups with exactly the same number in each group. (Have a look at the witch doubling in 'Frooby the Dragon' PowerPoint below.
Activity: Can you roll a dice and double that number? Use counters, lego bricks, or even pieces of pasta to show two equal groups and find the double. If you are really confident, roll two dice, add the total number of spots and then double that!
e.g. 3 + 4 = 7.... so...
Double 7 is 14.
Here is an activity sheet to help you practise.
