Before I share my activities from this week, I am excited to share that I was asked to co-host a webinar about Google for Education! I will be asked to share and discuss how I use Google within my classroom. I am looking forward to sharing my ideas and I would love for you all to join the discussion! Here is a link that will allow you to register for the event.
Review of Decimals and Using Base Ten Blocks
To activate prior knowledge and to review what students learned in fourth grade, we started off the week making decimals using base ten blocks. I started making baggies with bits and pieces of each type of block and then quickly realized, there has to be a better way! And there is! I created a Google Doc that I shared with my students on Google Drive. Students were able to work together to make decimals using the document I created. I could toggle back and forth between groups, making comments and suggestions, all in real time. I could also see misconceptions and observe students who were not recalling the information from fourth grade.
I allowed the students to work on this for about 10 minutes then we went onto whole group, where we reviewed the base ten blocks and how to make decimals using the blocks. We took notes in our journals and afterwards students could go back to their groups and apply the knowledge to fix their decimal documents.
The next day we moved onto expanded notation. Students knew that each place has a value, but I knew they would have trouble connecting that each number is composed of that place value times the digit. For example: 3.45 would be written as (3×1) + (4 x 0.1) + (5 x 0.01)
I wanted a hands-on way to visually see the process of multiplying the digit by the place value. I made a set of cards for each place value, from the tens to the thousandths. I copied the cards using colored paper. I also made an activity mat that allowed students to record a number and then construct the number using cards. At the end, students would record the expanded notation at the bottom. To save paper, I laminated the activity mats and had students use dry erase markers. To add a fun element, I had students generate numbers using dice.
