Halloween Maths Activity 1: Negative Numbers Trick Or Treat Adventure

This simple Halloween maths worksheet will help your primary school class practice using negative numbers in and fun and engaging way.

Sid and Susie the skeletons are both heading down a trick or treat path, and it is up to your pupils to work out how many treats each is left with after they complete their math filled journey.  

Each house along the path requires your class to work out the answer to a negative numbers based question. At some houses the calculations will create a positive number (a ‘treat’) and at others their calculation will create a negative number (a ‘trick’).

Susie the skeleton’s path is slightly trickier than Sid’s and has more difficult calculations, but this could mean more treats come the end of the journey! It is up to your class to decide which path they will take! Halloween maths activities don’t come easier to use than this!

How To Use This Halloween Maths Worksheet

You can print off the worksheet and get your class to tackle the path individually or in teams, or if printing poses a problem then simply put the sheets up on the interactive whiteboard and use maths books for answers.

Halloween Maths Activity 5: Bats Vs. Broomsticks Measuring Activity

Depending on whether or not the Autumn weather has truly taken hold, this activity is the perfect one to make the most of the last few rays of sunshine and to take your maths lesson outside. This is one of the most active Halloween maths activities we have on our list, so we know your pupils will enjoy!

Ask your class to make a paper aeroplane each, and then decorate it with either bats or broomsticks. Everyone is likely to have a slightly different method of paper plane construction, but this is exactly what we want for this Halloween maths game. If there are a few pupils that don’t know how to make a paper aeroplane though, you can find simple instructions of how to do so here.

How To Run This Halloween Maths Activity

All you need to enjoy this maths activity with your class is some paper, pens and a big dose of Halloween creativity.

Once everyone has made their paper plane, take them outside (or into the school hall if the rain is showing no sign of letting up) and let them fly! Then once everyone has released their plane it is time for some Halloween maths. Pupils can measure and compare the distances their planes have flown, and you can ask questions such as:

• How far did your bat/broomstick fly in metres?

• How far did your bat/broomstick fly in centimetres?

• Which bat/broomstick flew the farthest?

• What was the average distance flown by bats and by broomsticks across the class?

• What was the average distance of all the bats?

• What was the average distance of all of the broomsticks?

• Which type of plane (bat vs broomstick) flew the farthest distance when all of them are added together?

Extra Halloween Maths Activity Idea: To turn this activity into more of a competition amongst your class, why not add some extra monsters into the mix? How much further did the zombie plane fly than the ghost one? Is Frankenstein a better pilot than Dracula? The spooky possibilities are endless with this fun Halloween maths game!

Halloween Maths Activity 6: Frankenstein’s Friends – Roman Numeral Door Numbers

Whilst they are not the most important element of the curriculum for many teachers, by Year 4 pupils should be comfortable with Roman Numerals up to 100, so this fun Halloween maths game is a great way to challenge the Roman Numeral knowledge in your class.

In a similar vein to the negative numbers trick or treat adventure sheet, you can print off the worksheet and get your class to tackle the path individually or in teams, or if printing poses a problem then simply put the sheets up on the interactive whiteboard and use maths books for answers.

Halloween Maths Activity 7: Spider Web Area & Perimeter Greater Depth Investigation

Spider webs are everywhere approaching Halloween, but rather than accidentally walking into them in the playground, why not bring these clever creations into the classroom to help area and perimeter stick to your pupils like a fly in a web!

Halloween Maths Activity For Schools - Area and Measurement

How To Run This Halloween Maths Activity

Using the spider web shown here as an example, your class will need to work to find the area of one section of the spider web and then multiply this by the total number of sections around that layer to find the overall surface area of each layer of the web.

Then, they can repeat this for each layer of the web, eventually working out the total area of the web.

Simplify ThingsIf you are looking for a way to simplify this task, make each layer of the spider web a single shape, either in the form of a circle, square or triangle.
