Computational Fluency

Les Grandes Idées

4e: Pour acquérir une facilité à manipuler les nombres et des habiletés à effectuer des calculs, en particulier la multiplication, il est nécessaire d’analyser des régularités et des relations entre la multiplication et la division. 5e: L’habileté à effectuer des calculs et la facilité à manipuler les nombres s’étendent aux opérations avec des nombres plus grands (à plusieurs chiffres). 6e: L’habileté à effectuer des calculs et la facilité à manipuler les nombres s’appliquent aux opérations sur les nombres entiers naturels et sur les nombres décimaux. 7e: L’habileté à effectuer des calculs et la facilité à manipuler les nombres s’appliquent aux opérations sur les nombres entiers et les nombres décimaux.

Number Talks & Image Talks

Math talking tasks are great for warm-ups and daily numeracy routines. Students look at images and brainstorm with prompts. There are a range of access points, which develops growth mindset and self-efficacy in math. 


Images pour la causerie mathématique Version 1 et Version 2: Les élèves regardent une image des mathématiques dans la vie quotidienne et doivent la décrire avec le plus de manières mathématiques possibles.  Here’s a guide for getting the most out of number talks

3-Act Tasks (Three Act Task Explained)

These are 30-60 minute activities you can do to develop students’ observation, questioning, and estimating skills, as well as skills for calculating and solving real-life situational problems. They have 3 “Acts” with hints, photos, videos and reveals. Most videos include very few words in English, so they can be easily adapted for French Immersion, and the discussions help boost students’ oral French skills. 

Problem of the Week/Problème de la semaine 

POTW is a daily math problem, mostly based on real-life situations, released by the University of Waterloo Centre for Excellence in Mathematics each week. Here are some examples of POTW focusing on number sense. These are great questions to use for Vertical Non-permanent Surfaces (i.e. collaborative problem solving using whiteboards around the classroom). Each link includes the answer key. (À noter: les réponses sont seulement en anglais.)  

Problem A (Grade 4) in French

  • Quel nombre suis-je? – using place value and multiplication of 10 and 100 (p. 117-119) 
  • Clés pour décoder des messages secrets – using a code to spell words (p. 119-120)
  • L’addition et la soustraction – applying addition and subtraction to discover and “math”gic trick  (p. 124-125)
  • Sortie au théâtre – planning the number of buses needed for a field trip (p. 40-41) 
  • Mesurez-moi – comparing growth at different ages (p. 48-49) 

Problem B (Grade 5/6) in French  

  • Quand est-ce qu’on arrive? –  converting Astronomical Units to calculate the distance and time from earth to other planets (p. 7-8)
  • Ce puzzle a votre nombre! – solve many operations to make a crossword  (p. 19-20) 
  • C’est à peu près ça – finding numbers that will fit in blanks to meet the criteria for the sum (p. 21-23)

Other Innovative Computational Fluency Activities 

Multiplication by Heart by Mathigon and Math for Love is an interactive visual flashcard activity that shows numbers in groupings to help students visualize the math fact.  

Using Bead Strings to represent multiplicative reasoning and relationships to 100 (Video with Shelley Gray)

The Open Number Line is a measurement model where students may represent strategies and computational thinking beyond 100 on an interactive online number line.

Partial Product Finder allows multiplication to 50 X 50 to be represented as a rectangle or several rectangles, helping students develop strategies for multiplication of larger numbers. (e.g. 26 x 15 = (20 + 6) x (15 + 5).

Steve Wyborney Multiplication Course (for educators or students) is a series of very short Youtube videos that deepens learning about what multiplication is and offers many strategies for multiplying
