The Challenge This Code Breaker Challenge is made up of 4 challenge sheets, each containing three sets of questions about addition as well as an instruction section written in code. There is also a final challenge sheet for obtaining the master lock key. The Setup Ideally, the Code Breaker Challenge requires a box which can be locked with four three digit combination locks and one padlock. See the attached picture as an idea for the setup. It could however be done without this, but wouldn’t be quite as fun for the children. How to Use Fill the box with treasure, for example some sweets and then setup the combinations on each of the locks and lock the box with them and the master lock. Split the class up into four teams and provide each team with one of the challenge sheets. Start a timer of approximately 30 minutes (depending on the ability and age of your class). Each team works together to solve the challenge and tell the teacher the three digit code. If they got it correct, they may open their lock. If not, then they will need to check their answers. Once all four combination locks have been opened, or even after the first team has finished, provide the master lock challenge. If they complete it correctly and within the time, they can then have the master lock key to open the treasure box. Great Fun! The children absolutely love the Code Breaker Challenge and we repeat it at the end of every major maths unit. They really need to work together and check their work carefully if they are to succeed in opening the box and retrieving the treasure within. The documents is fully editable so you can use it as a template to create your own challenges if you like. You can also use it for other subjects as well, but it definitely lends itself to maths the most. I hope you and your children enjoy it as much as mine do! This challenge is one in many. Please take a look at my shop for other units. Thank you.

This worksheet involves 10 shape patterns of increasing difficulty. Children have to discern the repeating unit and then fill in the missing shapes to complete the patterns. There are a mixture 2D and 3D shapes and most of the patterns involve rotation and colour changes. LO: I can identify patterns in sequences of shapes. I can complete missing sections of patterns in sequences of shapes. This worksheet is designed to be used online as a Google Doc but could also be printed, however some of the shapes would be difficult to replicate just through drawing. I use it in Google Classroom and create a copy for each of the children to work on.

This is a spinning wheel which is made of two parts, an top wheel which has a window and a door and a bottom wheel which has the questions and answers on respectively. Instructions: a) Print out the template on card. b) Children then write an operation, for example, 3x6 in the inner section, and write the answer in the outer section. Complete each part of the pie with other operations. c) Cut out the sections of other top wheel except the dotted line which will be a fold for the door. (You may need a cuter or Stanley knife for this). d) Use a push pin to attach the wheels together so they will spin. Decorate the wheels and then cut out. Usage: With the little flap door closed, spin or turn the top wheel to reveal an operation. Try and answer it before opening the flap to reveal the correct answer. *I usually use this for children to review a the more difficult of the timestables but it could be adapted for other short question and answers that require a bit of rote learning. It just makes it all that more fun to do. *

This worksheet could be printed out, but was designed to be completed by children online in Google Docs. It’s made up of 4 questions, a bonus and an extension task. Each question involves a table shape with different numbers of cells shaded different colours. Children have to identify the fraction of each of the colours shaded. It builds in difficulty up to where the children then have to place the fractions in order of size. The bonus question involves ordering fractions with different denominators. It’s great for use in Google Classroom where every child gets their own copy. You can then easily check their individual progress live and then check their results.

This is a review for a maths unit on volume for LKS2. Four teams race to solve word problems involving volume so that they can open the locks on the mystery box. See the Code Breaker Template here for more details on what you need and how to setup this very popular activity.

This is a fully editable template for a break out style activity that I call Code Breaker. Pre-requisites: You will need at least 1 numerical combination lock and one regular lock (the master lock) and a box or even multiple boxes that you can use these locks on. I made my own ‘Mystery Box’ which has 4 latches for 4 numerical locks. Then the whole thing is wrapped up with a chain and locked with the master lock - a key padlock. I mostly use it for reviews in maths but it could be adapted for other subjects. There are so many possibilities with this. It does take a little time to setup but the children go wild for it every time! The Setup: a) Write questions which have a numerical answer. b) Decide on which numbers will be part of the code for that numerical lock. For example, add all the answers together and the last three digits of that result are the code. (This is for a three digit numerical lock). c) Change the code on the numbered lock to match. d) Write a short phrase for the master lock using numbers. Usage: a) Fill the box with random treasures. I usually put in some cool erasers and other stationery as well as several packs of crisps or sweets and a whole bunch of fake money. b) Split the class into teams and provide each with a sheet for a lock. Start the timer. c) Children then solve the code and then and open their particular lock. d) Those that solve their lock first can start working on the master lock phrase. After telling you the correct phrase, you can provide the key. *Sometimes I don’t let them get the master lock sheet until after all the other numerical locks have been opened. * Notes: The master lock page has a large image of a lock on it which obscures parts of the code, thus making it a bit more difficult. Also, each letter has four potential numbers to choose from which also adds to the difficulty in cracking a code. You can also make cracking the codes for the numerical locks more difficult by adding more operations on the end. For example, you could use an equation for the letters of each question and then depending on the result you could say that the code is only made up of odd numbers. You can also make questions which don’t have numerical answers by having a simple text to number cypher. The most basic would be to correlate the letters of the alphabet to the number in which they appear. For example, A=1, B=2 etc. If the answer is say, Holland, you could write a short note saying second letter so the children know what to look for and convert into a number. *I hope my explanations are clear, but if not, please feel free to message me or comment. It’s very worthwhile setting this up and once you have the templates filled in, you can reuse them each year as I do. *

This worksheet entails children finding objects in the classroom to first fit a certain length range - Less than, more than and between lengths. Second, it asks that children find other objects and record and measure the exact length using a ruler or tape measure. It also has a column where they can estimate or predict the length of the object. I usually use it as an follow up to an introduction to length, measuring and measuring tools. It’s perfect for teaching about the phrases; less than, greater, than, equal to as well as how to estimate and to measure length using various tools. The download comes both as a PDF and fully editable DOC, so you can make changes as you please.

Four A4 pages of general information about how we measure length and with what, as well as what units we use. Used as a wall display to act as a reference for the children, when they’re learning about length in maths. *The document is fully editable. *

This worksheet uses the game of darts to help consolidate knowledge of addition and subtraction. It can be used with or without a real board and darts. You could even use an online game instead. It really helps add some extra enjoyment to maths! The first section of the worksheet involves getting accustomed to the board - knowing what each section of the board is worth. This involves some multiplying by two and three for doubles and triples, but repeated addition could be used for younger learners. The second part of the sheet involves calculating a score of three darts and then subtracting that total from 101, which is this particular game of darts. The final part involves continuing the game and trying to finish with exactly zero. A professional game of darts usually finishes with a double but it could be a single number to make it more likely new players can finish. The worksheet comes in a DOC format, so most parts are easily editable.

This colourful worksheet is made up of 5 addition word problems of increasing difficulty. For each problem, the children are expected to draw a bar model using the template provided and then show their workings and answer, again using a provided outline. The final question involves children creating their own word problem for their friend to try and solve using the same methodology, The worksheet works even better if accompanied with manipulatives such as Base 10 blocks. The LO is for the children to be able to solve addition based word problems with the help of bar models. The document is fully editable so names, numbers and questions can be changed to suit your children’s needs.

10 multiplication word problems involving 1-digit and 2-digit numbers. The first 6 involved no exchanging but the final 4 do. The questions increase in complexity as they progress, leading up to 2 and even 3-step solutions. Numbers are all written as words and pictures are included for each question as well as enough space for the children to show their working and answer. Here is an example question: Alex bought five packets of cookies to share with his friends. Each packet contained eleven cookies but the last one had three missing because his sister had eaten them. In the end, how many cookies did Alex have in total? This worksheet can be printed off or even set for the children to do online as a Google Doc. The content is fully editable so you can easily change question content.

This worksheet involves copying 2D shapes & figures. The lesson objectives and tasks, taken directly from the worksheet, are as follows… LO: I can copy a 2D shape/figure exactly as shown. Task: Use this http://print-graph-paper.com/virtual-graph-paper tool to draw out the shapes/figures as shown below. Use the Snipping Tool on the computer to then copy and paste them into this document. You may also print off some graph paper and draw by hand. The shapes get progressively more difficult to draw as the worksheet continues. As an additional task you can ask the children to create their own cool looking patterns. This worksheet is designed to be used online as a Google Doc but could also be printed. I use it in Google Classroom and create a copy for each of the children to work on.

This editable concept sheet for Whiterose Maths is made up of four characters from White Rose and four speech bubbles. Children can use this to state different concepts in the unit they’re learning. The speech bubbles and character names are fully editable.
