Use this set of dominoes when learning how to match 3-digit numbers written in standard form and expanded form.
Expanded Form with 3-Digit Numbers
The practice of showing a number in its expanded notation is a meaningful way to communicate the place value of each digit within that number.
Help students understand place value with our Expanded Form Dominoes game, which challenges students to match numbers written in standard form with their expanded form.
- Place the ‘Start’ domino in the centre of the playing area. Shuffle the remaining pieces and place them to the side.
- Each player draws 3 dominoes.
- When it is your turn, look to see if you have a matching end piece.
If you don’t have a piece that matches, draw a domino.
- Play continues until all pieces have been used and the “End” domino has been laid.
Through this activity, students will show they can match a 3-digit number in standard form to its expanded form representation.
Tips for Differentiation + Scaffolding
A team of dedicated, experienced educators created this resource to support your maths lessons.
In addition to individual student work time, use this expanded form activity to enhance learning through guided math groups or whole class lessons.
If you have a mixture of above and below-level learners, check out these suggestions for keeping students on track with the concepts:
🆘 Support Struggling Students
Help students who need help understanding the concepts by completing this activity in a small group or 1-on-1 setting. Additionally, students can use a place value chart to help them determine the place of each number when determining the expanded form of a numeral. There is also a domino set available for 2-digit numbers.
➕ Challenge Fast Finishers
For students who need a bit of a challenge, encourage them to create their own set of expanded form dominoes. Make a copy of the editable version, delete the numbers, and give the blank template to your students to use. There is also a 4- and 5-digit version of this resource.
