This week we are learning about doubling and halving

## Take a look below at some of the activities you can do at home to get you started to help you with your doubles

Cool Challenge  With help from a grown up you can start by playing the double my finger game. The grown up starts by showing any amount of fingers on one hand. You must then try and copy the same amount. Once you have matched your grown ups number of fingers you work out what number you have doubled and what it equals. For example, if your grown up held 3 fingers up then you must do the same and work out what 3 + 3 =. This can be made easier if you hold your hand next to theirs whilst they count the finger held up.

## Double 3 is the same as doing 3 + 3 =

Mild Challenge  Roll a dice to generate a number. Work out what double this number is. Write it down as a number sentence e.g 2 + 2 = __ Use objects, fingers or a number line to help you. Repeat this a few times.
Hot Challenge  Ask your grown up to give you an example of a double and then write it down as a number sentence. For example, if your grown up says "double 5" you must then write the matching number sentence which would be 5 + 5 = __

Now lets move on to halving. Halving is sharing something equally between two groups or two people. When something is halved both groups or people must have the same amount each.

Cool Challenge  Take a look at the powerpoint below on halving. Once you have gone through it have a go at halving some things around your home with the help of a grown up. Ensure that they are split down the middle and both sides are the same and equal. For example:

• Fold paper shapes in half
• Cut paper in half using scissors
• Colour shapes in half
• With the assistance of a grown up cut fruit or vegetables in half using a knife
• Break a bar of chocolate in half
Mild Challenge We can also find half of groups of objects, like sharing sweets between 2 people to make it fair. Model this with counting objects. Share by counting out 1 for me, 1 for you until finished. We should have the same number of objects each. Encourage the child to say how many they have to start with (make sure its even) and then say what half of that amount is once they have shared their objects.
Hot Challenge Following on from the mild challenge, write what you found out e.g. half of 6 is 3. Make a list of the halving facts you have found out.
