There Is One Way To Skin A Cat....I Mean Solve A Math Problem

Second grade students have been working feverishly learning about new ways to add double digits. WE are going deeper into our learning and understanding the reasoning on how we are getting to our answers. This new way of thinking has teachers and students thinking deeply about place value and how numbers are made. Students are building each number so that they can see the value of each number and how we are adding the double digits together.

      

Students are building numbers using base 10 blocks showing the ones, tens, and hundreds place. This allows students to see how each number is made with concrete objects. We have also learned how to add double digits using place value on the hundreds chart by adding our tens and then adding our ones to find our sum. Through our discovery we have learned that there is more than one way to solve a problem, so we have also solved addition and subtraction problems using base 10 blocks, ten frames, and open number lines.

Every student is encouraged to use the strategy that best helps them solve the double digit addition and subtraction problems. It is a slow and steady process but we are seeing the light at the end of the tunnel.

Students are enjoying learning different ways and knowing that there is more than one way gives them options in problem solving.
