This is the fourth booklet I use with my Grade 4's throughout my Addition and Subtraction Unit. (See my store for my first booklet: Grade 4 Addition and Subtraction Centers- Making Tens with Hundreds, my second booklet: Grade 4 Addition and Subtraction Centers- 3&4-Digit Regrouping [Using Front End Addition] and my third booklet: Grade 4 Subtraction Strategies- Compensation). This is something that I have my students work on if they finish the main lesson’s activity early. It is something that makes those “early finisher” less work! My students know that when they are finished their math task, they are to work on their Jurassic Park. This allows them to have that rote practice but makes it a bit more fun!
-Activities involving a breakdown of how to use the extending the subtrahend strategy (involving steps on how to complete independently)
-Engaging games & activities to practice extend the subtrahend skills using 3- and 4-digit numbers (True or False activity, cut & paste, and a board game!)
-Reflection on the strategy
-Matching cards with recording sheet
Thank you and enjoy :)
