Base-10 Blocks

Students have been working with base-10 blocks during math time recently. These unassuming blocks are actually a powerful tool to help children develop a better understanding of numbers. I came across the following online guide for parents, and I think it's a useful resource for explaining base-10 blocks and the many other "manipulatives" we use during math time. Check it out when you get a moment. Students seem to enjoy using base-10 blocks, as it allows them to see numbers in a tangible form. So far we have used the blocks to help students add, subtract, and build their concept of place value. Students have done work with counting base-10 blocks in their math journals, as well as through math games during math workshop time and some of our online math games. The Unit 5 Everyday Math Family Letter (sent home last Monday) describes this, as well as other skills students are learning about in our current unit of math. 

In the photos below, students are using base-10 blocks to help them complete math journal pages and, the final photo, the student is using virtual base-10 blocks to solve a two-digit addition number story. 

Does your child access the Everyday Math games at home? If not, please encourage him/her to do so! Log-in information was sent home near the end of September. The directions to log-in are listed below. if you have lost/forgotten your child's log-in information, please let me know and I can send it to you again. There are some wonderful resources available!

Logging into Everyday Math Online

1. In a web browser, visit the home page at www.everydaymathonline.com. (You may want to
“bookmark” the address or save it as a “favorite” to get to it quickly in the future.)
2. In the Username box, type the LOGIN name from the Login Card that
your child brought home from school. Click the LOG IN button.
3. In the Student Password box, type or click the PASSWORD from the
Login Card, and click the LOG IN button. The teacher chooses the password format, but you
should see a form on screen that matches the format on the Login Card.

Your child may now use the features and components of Everyday Math Online. Enjoy!
