This week, second grade mathematicians kicked off a new math unit that focuses on whole number operations and solving number stories. Students will learn strategies to solve for multi-digit addition word problems. In the first few lessons of this unit students were introduced to comparison diagrams that will compliment the two diagrams; Change and Part-Part-Total diagrams that they have been using to solve number stories to date. Students also kicked off this new unit by exploring ways mathematicians can collect data. They also learned that they have lots of tools that they can use to present their data to others. Students tried fun data collection activities in class where they utilized record sheets, tally marks and numbers to keep track of toy car jumps, dice rolls and the number of pockets visible on the clothing they were wearing. Household items can offer students opportunities to collect data at home too! Items like coins, pantry items and/or crayon collections can offer a fun way to track items, practice recording data using tallies and create picture or bar graphs to present their data.
Lastly this week, second graders are growing excited to celebrate the 100th Day of School next Friday!
