Here is a great puzzle link http://www.kenken.com/ These puzzles are a Sudoku type with a twist instead of just making sure the numbers from 1-9 are in each column or row, these must add, subtract, divide or multiply to specific (given) numbers. Teachers can sign up for a free email every 2 weeks and recieve the puzzles (and answers ) ready to go!

When children are learning to multiply two digit numbers they are often told about tricks or about magic zeroes appearing! There is no magic – it is the way numbers work. Here’s a quick clip to show you how it can be taught so that children understand.
Here’s a fun game to start off: Maths paper, rock, scissors!
Level 1: two players each use one hand and the winner is the first to say the sum (+) of the fingers on both hands. Addition to 10
Level 2: two players each use both hands and the winner is the first to say the sum (+) of the fingers on four hands. Addition to 20
Level 3: two players each use one hand and the winner is the first to say the product (x) of the fingers on both hands. Times tables to 5 x 5
Level 4: two players each use both hands and the winner is the first to say the product (x) of the fingers on both hands eg if I put 7 fingers and my opponent 4 fingers, the winner is the first person to say 28. Times tables to 10 x 10.
>the difference between the fingers
>multiple players – play with three or more!
** Only allow zero to be used once by any player
Decimals can be a tricky topic for students. Here is a short video to show the power of using Linear Algebra Blocks (LAB or Decimal pipes or decipipes) to support your students’ understanding of decimals. I think every classroom should have these readily available for students to use.
If you would like your own set of decimal pipes please see the Products page.
I have also included a video I took many years ago in my classroom to show you how I used my one set of decimal pipes in a “fishbowl” scenario to introduce multiplying decimals.
An introduction to dividing by 10 using a number slider. The free downloadable template for the number slider can be found at TES resources (UK or Aus) or TPT (teachers pay teachers in the US). This is a great resource for teaching multiplying and dividing by powers of ten. Check out the You Tube clip that I made.
