Support your students in developing their number sense and visual estimation skills with this set of Estimating Quantities Worksheets. These engaging tasks encourage students to make quick, reasonable guesses based on visual groupings—helping to strengthen their mathematical thinking and confidence.

Key Learning Outcomes:

• ✅ Make and refine estimates based on visual cues
• ✅ Develop number sense through comparison and reasoning
• ✅ Justify estimation strategies using mathematical language
• ✅ Reflect on estimation accuracy to improve over time

What’s Included:

• Worksheets divided into four scaffolded sections:
• Estimate quantities with a quick visual scan
• Explain estimation strategies
• Compare quantities across images
• Check accuracy and reflect on results

Materials Needed:

• Printed worksheet sets
• Pencils or markers
• Optional: photos or real objects for extension activities

How to Use:

• • Model estimating with real objects as a warm-up
• • Have students complete each section of the worksheet in order
• • Encourage explanation using classroom estimation vocabulary
• • Review and discuss estimates and strategies as a class

Ideas for Classroom Use:

• 💡 Use as a warm-up during mental maths or number sense sessions
• 💡 Incorporate into small group work for strategy sharing
• 💡 Display estimation-themed vocabulary to support student explanations

Top Teacher Tips:

• 💛 Encourage students to use phrases like “I saw groups of...” to describe their process
• 💛 Create a classroom Estimation Wall to showcase photos and predictions
• 💛 Track student estimates over time to build confidence and fluency

Estimating Quantities Worksheets are a powerful way to build number sense and help students become confident in making mathematical predictions and justifying their thinking.
