What is Number Sense?

Here is an excellent article explaining how we think about and teach Mathematics has changed.

 If you are connected with the world of K-12 mathematics education, it’s highly unlikely that a day will go by without you uttering, writing, hearing, or reading the term “number sense”. In contrast everyone else on the planet would be hard pressed to describe what it is. Though entering the term into Google will return close to 38 million hits, it has yet to enter the world’s collective consciousness. Stanford mathematician Keith Devlin explains what it is.

Clothesline Math

Here’s a great idea for Middle and High School teachers! The Clothesline is a manipulatable number line that costs about $5.00 to construct and can be used to teach concepts in Number, Algebra, Functions (graphs), and Geometry.



Here is a video demonstrating some Clothesline activities:


Although these activities are designed for use in Middle and High School classrooms,  a manipulatable number line is also useful for exploring number concepts with younger students.

Seasonal Math Activities


There are many websites offering Christmas-themed worksheets, colouring pages, and free printables, but it is a little more difficult to find some seasonal activities that are not just pencil-to-paper tasks. Here are a few of them:


This is a collection of activities which includes Koch Snowflake, Penguin Math, Snowflake Activities, Snowman Problem Solving, Literature Connections (activities based on The Fattest, Tallest, Biggest Snowman Ever by Bettina Ling), Winter Glyphs, Winter Data Collection, Gingerbread Math Activities, Winter Coordinate Graphing, Holiday Problem Solving and samples of student work. These activities are most suitable for elementary students.


These counting, sorting, and matching activities are designed for early childhood education settings so would be suitable for Kindergarten students.


These free 2-player games could be used as part of a math centre in a primary classroom or for home practice. Included are: Addition Game, Subtraction Game, Multiplication Game, Division Game.


These integrated activities are best suited for elementary students, but could be adapted for older students. Included are snowflake math, estimation, counting, measuring, winter glyphs, and data collection & analysis.

Excellent Opportunity to Learn With Carole Fullerton!

Please note that School District 52 (Prince Rupert) has opened up a few spaces in some of their Carole Fullerton sessions to teachers in Coast Mountains. Available sessions are:

  • Demo Lesson/Discussion in a Grade 3 class (Nov. 16, 12:30-3:00)

Halloween Math Activities


There are literally thousands of Halloween-themed Math worksheets out there. They may seem like fun, but they are still worksheets! Here are a few non-worksheet Halloween Math activities:


Activities include Candy Math, Batty for Shapes, Seasonal Problem-Solving, and Halloween Estimation. Suitable for primary students, but could be adapted for older students.


Describes the following activities for elementary students: Pumpkin Math, Spider Math, and Halloween Data.


These are samples of Halloween word problems written by elementary students. They could be used as examples for students of all ages to write their own.


This is a computer game students can use to practice their addition, subtraction, multiplication, or division facts.


The following pumpkin-themed activities are described: Math Mat, Measurement, Symmetry, Glyphs & Graphing Ideas, Math-Literature Connections, Games, and Problem Solving.


These Math activities which use Halloween-themed erasers as manipulatives are geared towards younger students.


These Halloween-themed Math activities use dollar-store items as manipulatives. The activities described are more suitable for students in the primary grades but could be adapted for older students.

Using Lego to Teach Math Concepts


Here are just a few of the resources which describe how LEGO can be used to teach Math concepts:


This blog post describes how LEGO can be used to teach part-part-total thinking, building square numbers, fractions, multiplication & division, and mean, median, mode & range. There are some teaching tips and useful downloadable templates.


This is a list of links to resources which describe how LEGO can be used to teach counting, basic skills (number sense), addition, subtraction, multiplication, division, fractions, measurement, and algebra.


This post describes (with pictures!) how LEGO can be used to teach fractions, area & perimeter, multiplication, mean, median, mode & range, place value, spatial awareness, and fractions. There is a nifty downloadable LEGO/dice template here.

This is a short video demonstrating how LEGO can be used to teach fractions.


This is a collection of ideas using LEGO to teach a variety of Math concepts including counting by 1s, 5s, & 10s, number building, estimation, fractions sorting, statistics, area & perimeter, 3-D shapes, symmetry, algebra, and ratio & proportion. There are some downloadable activity cards and lots of teaching ideas for using LEGO in other subject areas as well.
