About this resource

Description

Every event has a reason behind it, and this what happens? cause and effect worksheet helps third graders find it. Cause and effect is how readers understand why things happen in stories and in real life: the cause is why something happened, and the effect is what happened as a result. Students practice spotting both parts and joining them into one clear sentence.

In Part A, students draw a line to match four causes, such as a forgotten umbrella or a strong wind, with the effect each one led to. In Part B, they read two short sentences and combine them into one sentence that shows the cause and the effect, using the word because or so. A cheerful picture of a melting ice cream cone goes with the first item. The second page is a complete answer key with model sentences. This 3rd grade cause and effect worksheet works well for literacy centers, morning work, homework, or a quick grammar and reading check.

What’s Included

  • Four cause and effect matching pairs
  • Three sentence-combining items using because or so
  • A complete answer key with model sentences

Why This Worksheet Helps Kids

First, matching causes to effects trains students to ask “why did it happen?” as they read. Second, joining two sentences with because or so shows how writers link ideas, a key 3rd grade language skill. Third, writing complete sentences builds stronger, more detailed answers on reading tests.

Ideas for Teachers and Parents

Before starting, act out a simple cause and effect, like dropping a ball, and ask students to name each part. After the sheet, have children write their own pair of sentences about something that happened at school today and swap with a partner to combine them. Keep this what happens? cause and effect worksheet handy during read-alouds and pause to ask what caused an event in the story.
