Develop your memory TransumA Back to School collection of activities from Transum Mathematics was a reminder of many activities I like and a source of some new discoveries. Looking at the Develop Your Memory suggestions, I noted Number Recall something which I think I’ll try with Year 7 when we look at Statistics. It is often said that the average person can remember 7 digit numbers; the Transum activity allows a choice of the number of digits so we’ll see how good our memories are! I rather like the Kim’s Game activity here too which led me to a collection of Kim’s Games on Transum including Angle Theorem Kim’s Game, something to try perhaps when reviewing Circle Theorems.

Additive Yohaku with rule

Yohakuu is a puzzle that will test your number sense and problem solving skills. Each Yohaku puzzle is either an additive or a multiplicative puzzle. You must fill in the empty cells such that they give the sum or product shown in each row and column as well as satisfying a rule if given.

Choose from 2×2, 3×3 or 4×4 puzzles.

Multiplicative Yohaku with ruleThese could be used as Starters or perhaps in form time.

Follow Yohaku on Twitter. Checking the Twitter stream I noted this algebraic puzzle below, an excellent idea. Try a little logic, where must c be placed for example.

Spirograph by Nathan Friend Spirograph by Nathan Friend

As a child my Spirograph was definitely a favourite toy so I was delighted to find this digital version, Inspirograph by Nathan Friend. Try altering the gears so that the fixed and rotating gear are the same size, or make one size a factor of the other, make the two sizes have a common factor, or not! Investigate.

You can change the colours too and create a work of Art!

For some more Spirograph resources including from the awesome Desmos graphing calculator see this post.

Find the Factors Puzzles – Iva Sallay

For a puzzle with a difference which requires both logic and multiplication try a Find the Factors puzzle from Iva Sallay on her Find the Factors blog. In this Find the Factors 1-10 puzzle can you place the numbers 1 to 10 in the first row and the first column to make the multiplication table work? Iva Sallay has clearly explained the puzzles here: How to Find the Factors.

New puzzles are published each week, I like the Excel files provided with puzzles of varying levels of difficulty. You will also find many hints and tips in the various posts. See Hooked on Factoring, for example, a post giving techniques for solving the puzzles and an Excel file of puzzles.
