Solving addition and subtraction problems to crack the safe code This is one of a set of resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within maths and science. This resource focuses on solving addition- and subtraction-based numeracy problems to find the code that will open a safe door. Do you have the maths knowledge to ‘crack the code’ and open the safe? Activity info, teachers’ notes and curriculum links In this activity, learners will solve three addition and subtraction problems. The answer to each problem will give two out of the six digits needed to crack the code to a safe. They will reinforce their addition and subtraction knowledge and apply this in a fun context. This activity could be used as a starter activity covering learning from the previous lesson, a plenary activity reinforcing learning that has just taken place, or as one of several activities within a wider scheme of learning focusing on addition and subtraction. The activity sheet includes teachers’ notes, useful web links, and links (where appropriate) to the national curriculum in each of the four devolved nations; England, Northern Ireland, Scotland and Wales. Remember, the downloads are all free! All activity sheets and supporting resources are free to download, and all the documents are fully editable, so you can tailor them to your students’ and your schools’ needs.

Using static electricity to make tissue paper cats ‘pounce’ onto a balloon This is one of a set of free STEM resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within maths and science. This resource focuses on making tissue paper cats ‘pounce’ and stick to a balloon through the build-up of static electricity. This activity could be used as a main activity to introduce the concept of static electricity, or as one of several activities within a wider scheme of learning focusing on electricity and its uses. Learners will first cut their tissue paper into small cat shapes. They could use different coloured tissue paper to make different coloured cats for more visual interest. Learners will then blow up and tie their balloons. The balloon should be blown up fully and tied so that no air can escape. If learners struggle to do this, the teacher could complete this step in advance. Alternatively, clips could be provided to seal the balloons. Learners will rub their balloon against their jumper several times to ‘charge’ it with static electricity. Following this, they can hold their balloon just above their tissue paper cat shapes. The cats should ‘pounce’ onto the balloon and stick to it. Why do you think the cats ‘pounce’ and stick to the balloon? How close does the balloon need to be for the cats to pounce? What is causing this to happen? This activity will take approximately 30-50 minutes to complete. Tools/resources required Balloons Tissue paper Scissors The engineering context Engineers use knowledge of science concepts in their everyday work to ensure they produce solutions that are safe, functional and meet the needs of their clients. A good grasp of basic concepts, such as how electricity and static electricity works, is therefore very important. Electrical engineers use their knowledge of how electricity works to develop new electrical products and systems. Suggested learning outcomes By the end of this activity students will have an understanding of the causes and effects of static electricity, they will understand how to use a balloon and a jumper to create static electricity and they will know that static electricity can be used to make paper stick to a balloon.

In this simple STEM activity for kids learners will investigate how a balloon can be used as a simple speaker. They will blow up the balloon, tap it and listen to how to sounds travel through it. They will then discuss the outcome of their experiment and explain why the balloon speaker works in the way that it does. This activity could be used as a starter activity to introduce the concept of sound and how it travels, or as one of several activities within a wider scheme of learning focusing on sound. Activity: Balloon speakers This is one of a set of free resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within maths and science. This resource focuses on using a balloon as a simple speaker to amplify sound. What happens when you tap the balloon? What can you hear and feel? Why do you think this is happening? This is a quick and easy STEM activity that will take approximately 15 – 20 minutes. The engineering context Engineers must understand how speakers work in order to successfully design products that use them, such as phones, music players and TVs. Sound engineers must understand how sound can be amplified and transmitted from one place to another. For example, at a concert. Understanding how speakers work is a very important part of this. Suggested learning outcomes By the end of this exercise students will know that vibrations from sounds travel through a medium in the ear. They will also be able to use a balloon as a simple speaker and explain how it works. Lastly, they will understand how pushing air closely together affects the volume of sound travelling through it.

Making cut-out 3D shapes and counting the number of edges, vertices and faces In this fun maths activity for Key Stage 2, learners will enhance their knowledge and comprehension of 3D shapes. They will cut out 2D nets for a cube, pyramid, cylinder, and octahedron, then fold them to form their corresponding 3D shapes. Through this process, they will also determine and count the number of edges, vertices, and faces on each shape. This activity can serve as a main lesson to develop an understanding of the characteristics of common 3D shapes. Alternatively, it can be integrated into a broader curriculum that focuses on the properties of 2D shapes, 3D shapes, and everyday objects. The engineering context Engineers must regularly use mathematics knowledge and skills as part of their everyday job. Therefore, they must have a good grasp of basic concepts, such as the properties of 3D shapes. Suggested learning outcomes By the end of this activity, students will be able to make 3D shapes such as cubes, pyramids, cylinders and octahedrons from 2D nets, and they will understand the difference between the edges, vertices and faces of a 3D shape. They will know the number of edges, vertices and faces on a cube, pyramid, cylinder and octahedron. Download for activity sheets and templates for free!
