2 worksheets on the topic of Iteration, with answers provided. Each worksheet is available as a pdf and a Word document, in case you want to make any changes.
In worksheet #1, all the answers are integers. I find this helps students understand the idea of a recursive formula, as they can perform all the calculations in their head.
Students are given a recursive formula and the value of x1, and must calculate the values of x2, x3 and x4. They then cross off their answers in the grid at the top of the page. Once theyâve finished the entire worksheet, there will be 6 numbers in the grid they havenât crossed off. These 6 numbers add up to 100. This is a nice, quick way for you to check that your students have completed the task correctly!
The content on worksheet #2 is more challenging as students will need to know how to use the ANS button on their calculators in a recursive formula. This is just a simple practice worksheet - students write down the values of x2, x3, and x4 in the spaces and then move on to the next question.
A couple of activities on Frequency Trees (aimed at KS3). The worksheets are provided in pdf and Word, in case you want to make any edits. Solutions are provided.
In âcomplete using the cluesâ, students are given 3 blank frequency trees, and 4 clues to go with each. They must use the clues to fill in each frequency tree. This requires some basic knowledge of fractions of amounts and ratio.
In âtrue or falseâ, students are given a partially completed frequency tree and must fill in the remainder - this requires some basic number facts. Using their completed frequency tree, they must then decide which of the 13 statements at the bottom of the page are true. This will require some knowledge of fractions of amounts, percentages of amounts, and ratio.
A simple worksheet on Dividing Mixed Numbers - nothing fancy.
12 questions for students to complete.
Once students have completed a question, they cross off the answer at the bottom of the page - if they canât find their answer, theyâve made a mistake somewhere.
There are 15 answers, so 3 wonât be used.

8 Time Series graphs and questions to accompany them. As well as questions on basic graph reading skills, Iâve also included questions that test other skills, for example averages, percentage increase, and writing one amount as a fraction of another. Solutions to all questions are provided.
Itâs possible to get all questions on one doubled-sided piece of A4 if you print 2 pages per sheet.
Apart from the football-related graphs, all data is completely fictional!
Iâve also uploaded the word documents so you can make any changes, if desired.
Pupils are given 36 integers (a mixture of positives and negatives) and have to put the numbers into a 6 x 6 grid so that every row and column is in ascending order. This gives them plenty of practice of ordering negative numbers by size.
Solving the puzzle requires experimentation, so when I have used this in my lessons, Iâve put the sheets in plastic wallets and let pupils write on top using a whiteboard pen.
There are many possible solutions; Iâve provided one. However, the smallest number (-28) must always go in the top left corner, and the largest (18) must always go in the bottom right.
A presentation I designed to help me deliver the âNumber Familiesâ task from nrich (https://nrich.maths.org/13123).
Rather than jumping straight in to set notation, it starts off getting pupils to list what they know about certain numbers. Then they imagine that numbers that share a certain property can be placed in the same âbucketâ. This idea of a âbucketâ is then used to introduce set notation.
An activity that I designed to make ordering fractions a bit more challenging for the more able in my group. Pupils are given 4 algebraic fractions, and must order them by size for particular values of the unknown. Solutions are provided.
A Bronze/Silver/Gold differentiated resource where pupils are given a list of decimals and a square grid. Pupils have to put the decimals into the grid so that each row and column is in ascending order.
In Bronze, the integer part of each decimal is the same. In Silver, the integer parts are different. In Gold, negatives are introduced. The grids get progressively larger as you move from Bronze to Gold as well.
Each puzzle has multiple solutions, but Iâve provided one possible solution to each.
Update 16/9/22: Changed the design of the tasks, but the content is the same.
28/09/22: New and improved Powerpoint uploaded!
The lesson starts with a quick recap of square and cube roots which all have integer values.
Students are then asked what the square root of 32 is. Itâs not an integer, but we can find an approximate value by determining which 2 integers its value lies. Some examples of how to do this are given (which are fully animated), then there are some basic fluency questions which can be done on mini-whiteboards so you can assess student understanding. There is a slide of questions for students to work on independently in their books.
To make things a little more interesting/challenging, there is also some work on solving basic quadratics provided. Rather than leaving the answers as a surd, I get pupils to give me approximate answers, so that they get some more practice estimating square roots!
Answers to all questions are given, and no printing is required.
4 questions that I created to challenge my more able Year 8 students when we covered solving equations with brackets. Requires knowledge of: how to find the area of a rectangle and triangle, how to divide a quantity in a ratio, and how to calculate the mean and range of a set of numbers. Answers are provided (and theyâre fractions to make things a bit trickier!).
A simple worksheet - nothing fancy.
Students are given 30 linear equations in a grid (all of the form ax + b = c), some of which have integer answers, and some of which have fractional answers. They have to solve the equations and colour in the boxes according to what type of solution the equation has. Like I said, this worksheet is nothing fancy so it doesnât make a picture when theyâve finished colouring!
Iâve provided answers as well.
I wanted something a bit more challenging for my more able Year 7s on the topic of âconverting between Mixed Numbers and Improper Fractionsâ, so I put together this activity. Students are given a sequence of Mixed Numbers and Improper Fractions, and must tell me what (simplified) fraction must be added or subtracted at each step to reach the next number in the sequence. Solutions are provided.
I really liked Don Stewardâs task on equable parallelograms (https://donsteward.blogspot.co.uk/2017/11/equable-parallelograms.html) but wanted some questions that were a little bit easier for my Year 10 group, so I designed these.
In each of paralleograms on the sheet, the area is equal to the perimeter. Students should use this fact to set up an equation, which they can solve to find the value of the unknown. Solutions are provided.
6 questions I designed to stretch the most able in my Year 11 foundation group.
I have provided an editable Powerpoint version of the worksheet, and a pdf which has 2 copies per A4 sheet.
Answers are also provided.
This activity is inspired by something I saw on the Mathspad website, but I wanted a simpler version to use in a first lesson with Year 7 on expanding double brackets. There are therefore no negatives in this activity, and the leading coefficient in the quadratics you obtain is always 1.
The students are given a table of algebraic expressions and 15 quadratics they are trying to create. They pick 2 expressions from the table, multiply them together and see if theyâve created one of the quadratics. If not, they try again! Each expression can only be used once, although most expressions appear multiple times in the table.
Iâve used this with a mixed ability Year 7 group, and it worked well. Weaker students can pick expressions at random and see what they get, whereas stronger students may start with the quadratic and ask themselves how they can create it - essentially factorising quadratics!
Solutions are provided.
I wanted something a little more challenging on the topic of Trapezia that still gave my students plenty of practice calculating areas, so I designed these questions. In each question, students are given a pair of trapezia and are told how their areas are linked (one is a multiple of the other). Students have to determine the area of one trapezium, use that to determine the area of the other one, and then finally use that to determine a missing value.
Sheets I and II are very similar, but sheet III is a bit more challenging. Solutions are provided.
