Description
How to Teach Classifying by Weight
The Weight Classification Worksheet helps students sort everyday objects by one physical property: how heavy or how light they are. Classifying by weight is a key science skill, because scientists group materials and objects by properties they can observe and compare. This weight classification worksheet gives 3rd grade students practice thinking about weight before they ever pick up a scale.
About This Worksheet
In Part A, students read eight words in a word box, including anchor, balloon, piano, and tissue, and write each one in the Heavy column or the Light column. In Part B, students read four sentences. Each sentence names one heavy thing and one light thing, such as a stone bridge and a paper kite, and students write both words on the matching lines. This 3rd grade classification worksheet works well for science centers, small groups, morning work, or homework.
What’s Included
- One printable weight classification worksheet for 3rd grade
- Part A: sort eight objects into Heavy and Light columns
- Part B: find the heavy and the light object in four sentences
- A complete answer key for quick checking
Why This Worksheet Helps Kids
First, it builds the habit of classifying objects by an observable property, which students use again with size, texture, and materials. Second, it asks children to compare two objects at a time, which prepares them for measuring mass and weight with real tools. Third, Part B ties the science skill to reading, since students must find the objects named inside each sentence.
Ideas for Teachers and Parents
Before the worksheet, pass around a few classroom objects and let students predict which ones feel heavy and which feel light. After they finish, ask students to name one more heavy thing and one more light thing they see at home. You can also use a simple balance scale to test two items from the word box.
