Comparing Numbers- Tens and Ones

In math this week we have been working a lot on comparing 2 digit numbers less than 100. We've been building the numbers using base 10 blocks, both hands-on blocks as well as virtual blocks on our iPads. We've been noticing and discussing how the 10s place is what helps us to know if the number is larger (as long as the 10s place numbers are not the same- we talked about what to do with that debacle as well). As a quick assessment this week, I gave each child 2 different numbers to build using the app, Number Pieces Basic. This is a great app for students to build, compare, add and subtract numbers with and best yet, it's free! So if you're interested for home, click the link above.

After creating their numbers, each student took a screenshot of their page and then imported that picture into the app, Doodlecast Pro which is an app that allows us to write on our pictures as well as record our thoughts (this is not a free app, but there is a similar one called Screen Chomp that is free). Students then had to tell what their numbers were, which was larger and explain the thinking that they used to know which number was larger. When we were done, we emailed our videos off to you, so if you haven't received an email from your child, please check your spam folder or contact me and we will resend it.
