Grade 3, Unit 21: Mass and Capacity (Ontario Mathematics)
- PDF
What educators are saying
Description
The Grade 3, Unit 21: Mass and Capacity supplemental resource is designed to meet the 2020 Ontario Mathematics curriculum expectations for mass and capacity. Students, in this grade, are asked to measure mass and capacity using non-standard units. The goal is that students will be able to solidify their understanding of how to appropriately and accurately measure mass and capacity while understanding how overfilling, underfilling and leaving gaps can impact measurements.
Quick Resource Overview
This resource features 6 lessons and 12 printable activity pages. You will need to supply additional materials not included in this resource including:
- Balance Scales
- Containers
- Non-Standard Units
- Objects to measure mass of
The specific expectations that this resource addresses are:
- E2.3 Use non-standard units appropriately to estimate, measure, and compare capacity, and explain the effect that overfilling or underfilling, and gaps between units, have on accuracy
- E2.4 Compare, estimate, and measure the mass of various objects, using a pan balance and non-standard units
There is no digital version of this resource available. The activities, assessments and lessons are meant to be printed and used in the in-person classroom.
Please be sure to view the preview of this resource for sample lessons and activities to see if this resource is the right fit for you and your students.
