Place Value and Partial Sums Algorithm
I created and used this PowerPoint with my 2nd grade students. It focuses on Place Value- Ones, Tens, and Hundreds and the Partial Sums Algorithm. You can also download my worksheets that go with the PowerPoint!
The PowerPoint includes:
-Chart showing hundreds, tens, and ones place value
-Circle the number in the ones place
-Circle the number in the tens place
-Circle the number in the hundreds place
-Directions for a place value game with place value chart

Rolling Into Sums (2nd Grade)
Make addition fun with this engaging game! This hands on activity reinforces the skills of adding numbers through an extended algorithm of partial sums while reviewing making comparisons. The game was designed in collaboration with two second graders themselves. The idea is for each player to simply roll 2 dice two times, recording the digits in the addition chart. Each player's goal is to obtain the greatest sum. Lastly, at the end, the children tally up the greatest sums to determine

Add by bridging through 100 up to 1000
Bridging through 100s encourages students to develop strong mental math skills by breaking down numbers into smaller more manageable parts. Students get to visualize the connection between different place values and understand the concept of regrouping or carrying over. It also provides students with an alternative approach to addition rather than relying completely on the standard algorithm. This strategy can be particularly beneficial for visual learners.
