Grade 3

Mathematics

Curriculum Overview

Throughout this grade, in order to promote a positive identity as a math learner, to foster well-being and the ability to learn, build resilience, and thrive, students will apply, to the best of their ability, a variety of social-emotional learning skills to support their use of the mathematical processes and their learning in connection with the expectations in the other five strands of the mathematics curriculum. 

Students identify and learn to manage emotions that they may feel such as pride, confusion, fear and excitement. For example, in algebra as they create and execute code that represents a mathematical situation. Multiplication is introduced using rows and columns, and students are expected to know x 2, x 5 and x 10. 

The mathematics curriculum is divided into six strands:

  • Social-Emotional Learning (SEL) Skills in Mathematics and the Mathematical Processes

  • Number

  • Algebra

  • Data

  • Spatial Sense

  • Financial Literacy

Suggested Activities

Complete these activities to consolidate learning across all curriculum strands.

  • Create your own definitions for 20 of the words in the vocabulary list. 

  • Can the number 225 be described as 200 + 20 + 5 or 2 hundreds, 2 tens, and 5 ones? Show how you know? 

  • Identify multiplication equations that are equal, such as 3 × 4 and 6 × 2.  

  • Calculate the change required for simple transactions involving whole-dollar amounts. 

  • You have $10, what would you go and buy if you could choose anything at all and why would you choose that item. 

  • Look for three-dimensional objects in your home and imagine what these objects would look like if they were taken apart or flipped around. 

  • You have 1 000 items (marbles), how many different ways can you organize them? How can you check your solutions? 

  • Find an item in your home such as a cereal box and unfold it to see the shape it creates and measure the area and perimeter. 

  • Find an object to weigh in your kitchen, estimate the weight of the object and how much it can hold. How could you measure the object’s weight?  

  • What time is it? Compare the time on a digital and analog clock? Draw the time in the format of your choice. 

  • Draw a picture to show that if two friends are equally sharing one apple, each will get one-half or two one-fourths.
