Use This to Help Teach Expanded Form
I know at this point in the year many of you have already taught expanded form. How do you get your students to maintain their understanding of expanded form? You could leave a reminder up all year long which doesn’t take up much space. Use your classroom number line, and add these special signs to your number line. Ta-da! This is even better than an anchor chart! You can choose from space saving triangular ones…
or longer ones so that the numbers are easier to see from a distance.
If you hang your number line low enough students can help add the cards to the number line, and you can print the signs on card stock. This way students can easily attach and reattach them with velcro onto the number line (great for long term use). Tape works fine too!
You can use your own store bought number line, or you may enjoy using this number line especially created for use with these signs that includes base ten blocks already attached like shown in the instructions above.
