# Calculation Nation – Rich, online math games for practice

The NCTM (National Council of Teachers of Mathematics) has a set of online math resources worth looking into. Check out Calculation Nation (calculationnation.nctm.org/)  for a series of challenging and engaging games for students in grades 3-9. Students will explore factors, prime and composite numbers, multiplication, area and perimeter, operations on fractions, solving algebraic equations and geometric concepts like tessellations and symmetry. Students can play  these games against the computer or even against another player somewhere else in the world!

A simple log in is all that’s required in order to play.

I’m sure you’ll find some worthwhile tasks in this set of carefully crafted materials.  Enjoy!

# Fair Shares – Teaching Division in Grades 4-7

Hello, all…

I am pleased to announce the publication of my latest teacher resource book called Fair Shares – Teaching Division in Grades 4-7. The book features tasks, games and problems for intermediate aged students focussed on making sense of division.

Through stories, models, pictures and words, students are introduced to the idea of division as sharing and division as grouping.  Lessons include opportunities for talk, for exploration and for practice in the form of games and engaging tasks across the grades.  The lesson sequences are designed to address division of whole numbers and decimal numbers, to make meaningful connections to fractions and decimals in context and to support students in seeing patterns in quotients.  Lessons map out how to use manipulatives to model division situations, and literature connections to introduce great division contexts. Match to the WNCP curriculum, Fair Shares – Teaching Division in Grades 4-7 outlines a range of assessment tools to allow teachers to gather evidence – quickly and without stress on the part of the students – to show what their learners know and can do.

Thank you, as always, for your support.

# Mental Math Game – Grades 3 and up

I came across an interesting game today in my perpetual on-line search for quality math games that promote thinking. It’s called Mission 211 – Mental Maths.

A video transmission from mission control’s Caleb explains the tasks at hand.  You must answer mental math questions as quickly as you can in order to collect biofuel rods and foil the evil roboids..!!  Best of all, Caleb provides strategies for solving the problems, if you need his help.  The strategies include “counting on”, “breaking down numbers” and “rounding” – what we might call compensation or friendly numbers.

The music and the heartbeat in the background (yes, really!) create a sense of urgency, and encourage you to complete the questions as quickly as you can.  If you need help, pressing the “HINT” button produces a mental math strategy to one side of the screen.  It’s a super helpful scaffold, and one that helps to make the numbers meaningful.  As you progress through the game, there are true or false multiplication and division questions as well – a nice blend of methods and ways of presenting content.

I like it!

Now – back to the game.  I’ve got some evil roboids to destroy.  🙂
