This activity is to help students practice two or three-digit addition. There are pages you can use to differentiate based on the readiness levels.
Students will pretend they are zookeepers and their task to solve the addition problems to find out which animals they are responsible for taking care of in the zoo. Students can then record which animals they are taking care of using the animals pieces. We created a class chart to record each students responsibilities. Students can be given rubrics to analyze their understanding and also help you to monitor their progress. The response cards be used to monitor which strategy students are using at a current time or to tell which strategy they like best.
In my classroom I have taught my students to add and subtract using different strategies other than the standard algorithm. We use base 10 blocks, number lines ( Jump), and decomposing numbers (splitting numbers into their expanded form). These follow the common core model and deepen students’ understanding of place value.
However there are extra pages included that do not specify a certain strategy to use to solve the problems.
