# 10 ideas for adding maths fun to Halloween!

## No tricks, just treats this Halloween

Sneaking maths lessons into Halloween activities and parties might sound more like a trick than a treat this Halloween. But, amongst the costumes, sweets and pumpkins, this popular holiday is actually a perfect time to help make learning maths even more fun for your children.

Try these 10 fun and easy ideas to add maths to the Halloween goodie bag this year…

## 10 sweet ideas

Children enjoy playing with their treats almost as much as they enjoy eating them. To take advantage of this enthusiasm, encourage them to weigh their bounty using a traditional bathroom scale, count individual pieces and guess the amount of calories in the whole bag. They can also divide the treats into categories, such as chocolate, hard, soft…

### 2) Bake maths into the Halloween fun

As you know, cooking with kids is a treat for them, but its also a maths teaching opportunity for parents. Invite them into the kitchen to make toffee apples or a pumpkin pie, letting them take the lead on measuring the ingredients. To increase the level of difficulty, challenge them to calculate the amount of ingredients needed to double the recipe or introduce the concept of ratios. For example, what is the ratio between the sugar and pumpkin?

### 3) Mimic the mathematicians

Inspire your children to reach their highest maths potential by inviting them to dress up as famous mathematicians such as Albert Einstein and Sir Isaac Newton. Or why not dress up as one of our loved Maths-Whizz characters such as Wincey or Super Ant?!

### 4) Rack up the repeats

Pick one of this year’s most popular costumes – witches, ghosts or ghouls – and keep track of how many times you see duplicates. You could make this a contest between a number of children – the winner receives bonus treats!

### 5) Count the cash

Between buying costumes, sweets and pumpkins, Halloween costs can add up. Discuss with your children how much money the family spends on Halloween every year, how much the country as a whole spends, and how money can be saved with acts such as trading costumes with friends.

### 6) Speak about spooky maths facts

Bats can consume nearly 50 percent of their body weight in food each night. The thread of the orb web spider is extremely elastic and can be stretched 30 – 40 per cent before it breaks! Discuss these and other spooky maths facts.

### 7) Predict the popcorn

This simple but effective game is particularly fun at parties. Just fill a jar full of popcorn and have the children guess the number of individual pieces. The person closest to the actual amount wins a prize.

### 8) Marvel in the geometric genius of spider webs

Spiders use silk in their abdomens to spin geometrically complex creations to catch their prey. Different spiders produce a wide variety of shapes. Parents can print pictures of various webs – spiral orb webs, cobwebs, funnel webs, tubular webs, sheet webs and dome or tent webs – and discuss their similarities and differences.

### 9) Wade into water measurement

If you plan on bobbing for apples, mark a line on the container where you want the water to reach. Ask the children to estimate how many litres of water it will take to reach the line.

### 10) Count the days until the Christmas holidays

Once all the treats are collected, break out the calendar and count the days until Christmas. How many months? How many weeks? How many days? This exercise is a great way to cap off Halloween while sneaking in one last maths lesson!

So don’t let addition, subtraction and estimation be more frightening than ghosts, goblins and ghouls for your children this Halloween. Utilise these tips and formulate your own for a wickedly Whizzy holiday!
