Solve addition and subtraction word problems1, and add and subtract within 10, e.g., by using objects or drawings to represent the problem (1Students are not required to independently read the word problems.)
General Information
Subject Area: Mathematics
Grade: K
Domain-Subdomain: Operations and Algebraic Thinking
Cluster: Level 2: Basic Application of Skills & Concepts
Cluster: Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from. (Major Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Help Pick Your Class Pet:

In this Model Eliciting Activity, MEA, the class receives a letter from the principal informing them they will be getting a class pet. They need to determine which pet to pick based on the data.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem, while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought process. MEAs follow a problem-based, student centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.
