Place Value/Numbers to 40+


  1. Subtraction from 50:  Keep subtracting numbers until you get to the target number.  If you get it wrong, you'll have to start over!
  2. Meet Lord Voldemath:  Try to answer the questions before the other wizard does - pick a level that will be challenging to you!
  3. Learning with Base 10 Blocks:  Make the numbers that is asks - when you get 30 correct (with the tally marks), you're done!
  4. Balloon Pop Order 0-100:  Pop the balloons in order from smallest to biggest.  See if you can beat 19,038 (Mr. Knaus' high score ... so far!)
  5. Balloon Pop Greater/Less/Equal: Pop the balloons that completes the sentence.  See if you can beat 46,534 (Mr. Knaus' high score ... so far!)
  6. Numbers to 1000:  Use the hundreds blocks, ten sticks, and unit cubes to figure out how many cubes there are all together.
  7. Powerlines (Level 1):  Make sure that all of the numbers in all of the lines add up to the target number.  After you finish level one, click here for level 2, and here for level three (you need a password from level 1 to go to level 2 - same for 2 to 3).  Be patient and try LOTS of combinations.  It's not easy... but it's fun!! J
