GOAL: Moving students toward computing problems quicker, easier and with a better UNDERSTANDING (number sense and place value)

Click on mini movie to see the strategy in action by a 2nd grade student...

• # Using ten frames

A ten frame is available on the main problem solving page. You can use pennies, buttons, beans or anything else to work on it.
• # Using base ten blocks

You can use the virtual manipulative library at home. Students can also draw them.
• # Counting by 1's on the 100 chart

There is a 100 chart available on the main problem solving page.

• # Number strings (negative number)

An easier way is to leave the first number whole and ONLY break apart the second number.  You may need to break it apart several times.
• # Open number line adding it up

This strategy uses addition to solve a subtraction problem.
• # Open number line with little jumps

Since we have created this video, we realize that the larger numbers on the numberline should always be on the right.  So the student should have written 88 on the right side and then worked right to left like subtraction would do on a number line.
• # Open number line with big jumps

Students need to be careful not to jump beyond the target number.  See next video.

• # Open number line with big jumps going too far

This video also has the numbers on the wrong place on the numberline.   The smaller numbers should be on the left and the larger numbers should be on the right. It seems like we learn each year along with the students.
• # Counting back

Most second graders are successful with this by the end of the year.
