## What Does It Mean to Estimate in Maths? – Kid-Friendly Definition!

As students are introduced to the term ‘estimate,’ they often are asked to guess how many gumballs are in a jar or how many blocks are in a box. This helps students to make a reasonable guess of an approximate amount. As students move to different year levels, estimation still, in fact, means to make a close guess or approximation, but this is done with the 4 operations: addition, subtraction, multiplication and division. If you are looking for an easy way to explain the term ‘estimate’ to your students, read on for a simple definition!

To ‘estimate’ means to make a thoughtful guess by rounding or compatible numbers to determine an approximate answer.

## Estimation Activities for Your Maths Class

Teach Starter has put together a set of estimation task cards to help your students refine their understanding of estimating products with whole numbers. This set of task cards comes with 24 questions that cover:

• Rounding factors
• Using compatible numbers
• Listing factors that could result in an estimated product
• Word problems
• Determining which method gives the most accurate answer

This teacher-created resource also comes with a recording sheet for your students to write down their answers and an answer key for quick and easy grading!

If you are ready for your students to use these task cards when reviewing estimation with multiplication, head on over to the green download button. You will find the quick-print PDF file or the editable Google Slides file here. If selecting the Google Slides option, please note that you will first be prompted to make a copy of the resource to your personal drive before accessing.

Consider printing the task cards on thick card and laminating them to ensure they will last for many years to come! Task cards can be kept in an organiser box, envelope or attached with a binder ring.
