This activity is aligned with third grade common core standard MACC.3.NBT.1.1: Use place value understanding to round whole numbers to the nearest 10 or 100.
This activity is designed for students to use independently or in a small group setting. It is a great way for students to practice rounding numbers in the tens, hundreds, thousands, ten thousands, and hundred thousands place value.
The matching game cards are labeled with numbers and letters. Students must match a number card to a letter card. They can record their answers on the student answer sheet provided. Students can also check their working using the answer key provided.
I have included two answer keys. One is with plain text and the other is in a QR code format. This code can be read using a QR reader app. on a smart phone or hand held electronic device with a camera. You can download a free one from the app store.
*** My students LOVE using my classroom iPod touch to check their work with the QR reader. I taught how to properly use the app in small group one day and they were so excited. I find that it really motivates students to get their work done!!
