# Base Ten Blocks Part 2: Center Ideas and Guided Math Group Lessons

Base ten blocks are great manipulatives for practicing place value. Here are 10 of my favorite virtual base ten sites! I would use these in three ways. First, I would use them as whole group instruction on an interactive board. Second, I would have the students work on them during center time at the computers. Third, I would pull small groups to the computers and hold some guided lessons there using these sites.

1. http://www.learningbox.com/base10/BaseTen.html ( I like this game, especially the drumroll and how everything reinforces place value)

2. http://www.learningbox.com/base10/CatchTen.html (this is fun but I never can seem to get the bear to catch ten!)

3. http://www.learningbox.com/base10/Estimation.html (great for estimating amounts)

4.http://ejad.best.vwh.net/java/b10blocks/b10blocks.html (be sure to read the instructions at the bottom of the page…great for smartboard teaching)

5.***** http://ulm.edu/~esmith/nctmregional/blocks.htm (this is an excellent resource for teaching operations with virtual base ten blocks)

Happy Mathing,

On Thursday I had to do an impromptu math lesson for my third grade class. I RAN for the Base 10 blocks!! I gave them addition problems using three digit numbers. I had the students show me place value in addition to doing the math. Great solution to a last minute problem!
