Virtual math tools

by C. Elkins, OK Math and Reading Lady

Every once in a while you come across something wonderful, and you want to share with your friends.  Well, I am doing that with this FREE website.  It is

Here is what you will find.  Click the i on each app and you get great visual instructions about the tool bar at the bottom of each app.  These can be used on your Smartboard as well as installed as an app on a laptop or ipad, etc. A few of the apps have a share / copy feature (a box with an arrow coming out). All of them have a writing tool to accompany the app.

  • Fractions: Fraction bars or circles
  • Geoboard:  3 different boards, put stretchy bands on (no more worries about breaking them with this app), use for area, perimeter, shapes, arrays, area of irregular shapes
  • Clock: Program the hands and the clock (Roman numerals, minute guide), shade parts of the clock, show elapsed time
  • Math Vocabulary Cards:  Great for review or quiz. Adjustable for different math topics and grade level. 3 parts on each review question:  Term, definition, picture
  • Money Pieces:  Display and hide coins.  The coins can be shown as part of a block to relate to base ten blocks. The coins do seem a little small in size, however.
  • Number Frames:  5, 10, and 20 frames, 100 grid, counters, and objects.  The 100 grid can be adjusted to make any size array (up to 10 x 10).
  • Number Line:  Use for skip counting, addition, subtraction, fractions
  • Number Pieces:  This includes base ten pieces. These can also be used to show the area model for multiplication.
  • Number Rack (aka Rekenrek):  A great tool for primary grades. Based on use of 5 and 10 as benchmark amounts. Use 1-10 Rekenreks. Count by 5’s, Count by 10’s. Practice sliding the beads – it’s fun!  Here is a link from my blog on ways to use a Rekenrek:
  • Pattern Shapes (Blocks): Compose and decompose shapes. Create using the blocks: Duplicate, rotate, change colors! The sillouette shapes enable you / students to use blocks to fill in.  Plus for intermediate grades:  There is an angle measure tool. Measure angles of the polygons presented.
  • Partial Products Finder:  Make arrays. Slide the bar on the bottom or side to partition the rectangle into smaller parts. Tap on a section to see a different color.

I will add this link to my instructional resources for future reference.  Enjoy!

I’ll get back to phonics next time.  Have a great week!
