NEW Resource! Proportional Reasoning in Grades 4-8

proportional-reasoning-coverFor those who have been patiently waiting (and lovingly nagging!) I am happy to announce the publication of my newest math teaching resource: Proportional Reasoning in Intermediate for Grades 4-8, available now through my online store.

This resource for teachers of Grades 4 to 8 presents more than 250 pages of open-ended lessons, meaningful practice, games, literature connections and a wealth of problem-solving contexts for supporting students to make sense of fractions, decimals, percentages, ratios and proportions. Designed for today’s diverse classrooms, this resource offers a range of tasks to promote proportional thinking through intentional development of mathematical language and the use of key manipulatives. Colour tiles, Cuisenaire rods and tangrams are used to model and make connections within and between concepts.

In the first section of the resource, students will explore three models – set, area and linear – for representing and describing, comparing and ordering fractions. Students will learn to convert between fractions, decimals and percent and to apply these skills to problem situations, including measurement, tax, discounts and data management. Next, students learn to add and subtract fractions, to solve proportions using a range of strategies (involving both mental math and the appropriate use of technology) and then finally to multiply and divide fractions.

Assessment tools are threaded throughout the resource to allow teachers to keep track of student progress and to make instructional decisions.   

 
 
 
 

Proportional reasoning IS the math we do every day.  This resource provides an access point for all.

 

Enjoy!

Maintenant disponible en français!

Finally … French translations of my latest books are now available!

Je viens de traduire mes deux ressources de bonnes questions — “A Year of Good Questions for Grades 2-4” et “A Year of Good Questions for grades 5-8” — afin que mes collègues d’immersion aient des ressources françaises avec lesquelles travailler. Merci pour vôtre patience!

In these new French translations of the English originals, you’ll find more than 200 open-ended and engaging problems for french immersion students from primary through middle school.  All are posed in French and explore important mathematical concepts across the grades.

Bonnes Questions primaireThe first book: Bonnes Questions: Une année de bonnes tâches mathématiques pour les élèves de 2e à 4e is suitable for late primary students (grades 2-4) and features operational tasks, measurement tasks and pattern tasks of increasing complexity, posed in French.

 

Bonnes Questions intérmediaresThe second volume: Bonnes Questions: Une année de bonnes tâches mathématiques pour les élèves de 5e à 8e is perfect for middle school immersion students (grades 5-8), with a focus on proportional reasoning, algebraic thinking as well as operations on integers, fractions and decimals to name a few.

Engaging problems and choice make these volumes the perfect conversation starter for our immersion classrooms, promoting oral language development and mathematical thinking …en même temps!

All are available from my online store.

New For Primary! Good Questions: A Year of Open-Ended Problems for Grades 2-4

 
Hello all!

For those of you who have been waiting ever so IMG_4295patiently, I wanted to let you know that I have completed a primary companion to the Year of Good Questions for Grades 5-8 resource released this summer.

A Year of Good Questions for Grades 2-4 is the late primary version of this stand up calendar of problems — one for every day of the school year!

Like its intermediate counterpart, this compact but potent book comes with an easel so you can set it up on your desk and flip from one rich problem to the next, posing open-ended questions of your primary students.

Good Questions: A Year of Open-Ended Math Problems for Grades 2-4 is a problem-a-day resource that includes rich tasks ideal for grades 2, 3 and 4. Organized by topic and structured in problem sets of 5, this simple to use teacher resource includes 200 mathematically important questions to engage your students in deep thinking. For only $25, it’s a reasonably priced way to stimulate and promote mathematical conversation!

Operations, measurement, proportional thinking and patterns are featured in this calendar of problems. Each one engages students in thinking flexibly, critically and creatively to solve tasks of varying complexity.

Magic Squares – Online

Here’s a fun little game for primary classrooms… The Magic Squares game provides students with a total for each row and column, as well as a few key starting numbers.  Use the magic wand to place the correct digits from the set of numbers at the bottom of the screen.  Double click to grab and then place the correct numerals in the grid.

Each game sets a different total for the rows and columns, so students can choose a number that makes sense for them before beginning.

The challenge of finding a sum for 3 addends is a good one for late grade 1 (when the digits without images to accompany them make sense) through grades 3.

Have fun!

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.  🙂

Fun online game – working with doubles

I was cruising around this morning and came across some of my favourite games for practicing mental math strategies. Check out this cool game called dinosaur dentist…  It asks kids to find the double fact that matches the number of teeth in the dinosaur’s mouth, then to subtract one tooth (the black one) to find the doubles less one fact!  The pain-free dino does a dance to celebrate afterwards.  Very cute!

The next game is called Woodcards.  It uses the idea of partitioning to help kids see how they can apply doubles strategies to much larger numbers.  The cards with the digits printed on them slide apart to help students remember they are talking about tens and ones!  It pairs the numbers with abacus sets to represent the values. This is a good game for late grade 2 or grade 3.

They are part of the most amazing and conceptually grounded sets of games for developing number and operational sense in primary students.  They are really fun (yes, even for me!) and the graphics are great too.  Check them all out at ICT Numeracy Games.  Developed by James Barrett to match the very evolved British curriculum, they are focussed on mental math strategies and help target those ideas in early learners.

Have fun!
