There are three Cross-number Puzzles provided in this worksheet resource: Puzzle A, Puzzle B and Puzzle C. They are in increasing order of difficulty. All clues involve a mixture of addition, subtraction, multiplication and division of fractions. Puzzles A and B involve operations with two fractions or mixed fractions. It is possible to complete each of these two puzzles by ignoring the division clues. The clues in Puzzle C all involve operations with three fractions. Knowledge of the order of operations is essential to solve this third puzzle.
There is an explanation given on each puzzle sheet of how fractions or mixed fractions are to be entered in the grid
The full answers to the three puzzles are given in the Notes for Teachers along with a few relevant notes regarding the puzzles.
Students use the cut-out sheet to make a set of 12 pentominoes. This puzzle pack has 20 shape templates. Each shape can be created using all 12 pentominoes. The shapes are themed as rectangles (including squares) with holes in them.

Diagrams of incomplete factor trees are given for the student to complete. There are then
follow-on tasks exploring the fact that one number may produce differently structured trees.
In the Teacher's guide an investigation is outlined based on the activities covered in the worksheet.
All answers are given.
Students explore the symmetry properties of the pentominoes then create symmetric shapes using pairs of pentominoes.
A cut-out sheet is provided for making the set of pentominoes. There are then 4 worksheets which include finding axes and centres of symmetry, completion of a pentomino summary sheet, discussion of bilateral and rotational symmetry and order of symmetry.
There are 3 pages of a Teacher's Guide which give full answers to all the activities. Possible approaches to lessons are given and useful extension activities are outlined.
This word search grid contains the names of 50 famous mathematicians. Students are asked to give the direction, coordinates and name. Geographical directions of the compass are used for how you read the name and coordinates of the position of the starting letter are asked for. Templates for filling in this information are given below the grid.
The three page Teacher's Guide contains the full solutions, guidance on possible approaches and uses for the word search and also a page of crib sheets whose use is also explained in the notes.
This comprehensive pack contains resources to introduce students to Conway’s Game of Life. Watch configurations of dots die, survive and give birth. This recreational mathematics topic has fascinated thousands of people since its discovery in 1970.
The pack contains four worksheets with student activity Challenges, a 5-page Teacher’s Guide with answers to all the Challenges and an accompanying suite of 4 Grid Templates. It is suitable for students of all ages and ranges of ability.
The Guide also gives advice as to suitable classroom approaches, further extension work and reference to videos and software.
Worksheet 1 introduces the idea of Neighbours, Worksheet 2 focusses on death from loneliness and overcrowding. Worksheet 3 tackles the birth of dots. Then Worksheet 4 brings all the rules together and the activities focus on finding the next generation for various configurations. Still Life patterns are also explored.
The emphasis throughout is on activity, exploration and extension work. Much of the activity is suitable for group work.
Reference is made to suitable motivational videos and to an excellent free open-source software package (Golly) for further exploration.
This resource consists of two cross-number puzzles suitable for Year 6 upwards (P7 upwards in Scotland). Geometric diagrams are given illustrating the first few triangular numbers. To solve both puzzles the student will need to calculate particular triangular numbers, The largest required is the 41st. Clues use a basic algebra subscript notation for each triangular number.
The Teachers Guide outlines three possible approaches to the completion of the worksheet ranging from "brute force" calculation to more investigative approaches involving the triangular number formula.
The answers to the puzzles are also supplied in the Teacher's Guide.
This resource consists of a cross-number puzzle whose solution involves the calculation of hexagonal numbers. Geometric diagrams are given for the first few hexagonal numbers. Students will then have to devise methods to calculate larger such numbers.
The Teachers Guide outlines three possible investigative approaches to these calculations. One involves generalising using the given geometric patterns. The other two approaches involve investigating numerical patterns which then leads to the construction of a nth term formula. One is through patterns in a difference table and the other involves patterns in the numerical factors of the hexagonal numbers.
The answers to the puzzle clues are also given in the Teachers Guide.
In the first activity students complete the given factor trees. Further activities involve students creating similarly structured factor trees for further numbers then differently structured trees for all the previous numbers. Suggestions are made to link the activities to the prime factorisation of numbers.
The Teacher's Guide supplies answers to all the activities with a few additional notes.
Students have to complete a cross-number puzzle whose clues are all the addition of two fractions. Instructions are given on the worksheet as to how to enter a fractional answer in the grid.
The answers are given in the Teacher's Guide along with a few relevant notes regarding the puzzle.
This resource consists of 5 worksheets and a 6 page Teacher’s Guide. These worksheets explore the amazing symmetries occurring in the decimal expansions of prime reciprocals. Students investigate the cycles of digits in these expansions and complete beautiful cyclic diagrams, templates of which are supplied in these worksheets. The primes 3, 7, 13, 17, 19, 23, 29, 31 and 37 are explored. Hidden patterns are revealed and a connection between the number of cycles and the length of the cycles is discovered.
The completed diagrams are given in the Teacher’s Guide which also contains the outline of an investigative approach to the topic. Details are given of the various stages of the investigation and how the worksheets may be incorporated. Various extensions are suggested including the use of a spreadsheet.
This is a fascinating topic which will provide rich and rewarding mathematical experiences for the students.
