# Fractions, decimals and percentages webinar recording

I recently presented a webinar for the Global Math Department. It is just under an hour – filled with lots of practical things for the classroom and what to look out for when teaching these concepts. Enjoy! Click here to watch FDP webinar recording

# Almost no rote required – Webinar recording

Earlier this year I presented a webinar for the Global Math Department. Here’s the link to the recording that is about an hour.

# Division / Sharing resource

Scaffold the teaching division / sharing: Use this template to teach sharing or division. For example if you were just starting out with 15 ÷ 3 = 5, your student has 15 counters to share between 3 people so would start going down the 1 for each group (3 counters) then check if they could go again with the 2, yes! and again, and again and again –  a total of 5 times.

I have also made a short 5 min clip to show how it works!

This scaffolds the structure of short division with the 3| on the outside of the vertical line, the |15 on the inside and the answer above.

# An easy way to teach division

Division is one of the hardest concepts for students to understand (other than half for you and half for me!). Here are a few alternative strategies other than rote to support your students. Check out this video to improve your teaching of division.

# Twos and Tens

This video shows you how to teach multiplication simply, using strategies. The only strategies that you must ‘learn’ by heart are doubling and 10 groups all the rest follow on from those.
Single and double digit multiplication are also shown using Multiplicative Thinking Blocks.

# Ken Ken

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!

Happy Ken Ken-ing, C

# No magic zeroes here!

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.
