Happy New Year, Everyone!
I am pleased to announce the release of my latest resource, Sums and Differences – Teaching Addition and Subtraction in Grades 2&3. This teacher resource is matched to the WNCP curriculum and addresses the operations of addition and subtraction to 100 for grade 2 and to 100o for grade 3. Designed to be used by teachers of combined grades – or by anyone who has a range of learners in their classrooms – these lesson sequences focus on the big math ideas of adding and subtracting! Each lesson asks students to engage with place value in concrete, pictorial and abstract ways, while practicing and developing fluency with the operations. Word problems, games and written practice are included to ensure students hone their skills and deepen their understanding of addition and subtraction with bigger numbers.
The resource includes all the line masters, game boards, written practice and teaching materials required to support your students in becoming proficient with addition and subtraction in ways that are consistent with the curriculum and which promote number sense.
This 220 page resource is just $40 plus shipping. Click here to order!
PS – The companion resource for grades 1&2 is also available for purchase. Read about it by clicking here.
PPS – My sincere apologies. I have discovered 2 errors in the book. One comes on page 167, in the game called “Three in a Line – Subtracting hundreds, tens and ones”. The wheel at the top of the page and the differences below don’t match. 😦 I’ve attached the replacement game here for you.
Likewise, I’ve had some feedback about the “I have…, Who has…?” game in the early pages of the resource. I’ve re-created it and uploaded the replacement here.
Thanks for your patience and understanding…
I thought I’d post an autumn-themed game on the blog this week for my colleagues in kindergarten. The game is called Falling Leaves, and it’s based on a game from the BEAM website. In my version of the game, students start with 15 unifix or stacking cubes in their own colour. To begin, Player 1 rolls a regular 6-sided die and puts a cube on the leaf with that numeral. Then Player 2 has a turn. If there is already a cube in that leaf, students stack their cube on top of the one that’s there, to make a tower.
At the end of the game (when all of the cubes are used up), players scan to see which of the towers has their colour on the top. Those towers are collected and snapped together. The player with the tallest tower wins!
In this game, pink is playing green. Green collects all the towers with green on top. Pink collects all of the towers with pink on top.
Stacked together, it’s clear to see that pink wins!
Enjoy… And happy fall!
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. 🙂
PS – Play the game in FULL SCREEN MODE to avoid silly advertising…
