In this Unit of Study…

Students will model the action of put together to represent addition. They will solve contextual word problems (put together total unknown and both addends unknown) involving familiar scenarios with sums up to 10 and differences up to 10. By the end, students will be able to explain the strategies they used to solve addition problems by using spoken words, concrete, and pictorial models, and expressions/equations.

B.E.S.T. Benchmarks:

  • MA.K.NSO.2.1 Recite the number names to 100 by ones and tens. Starting at a given number, count forward within 100 and backward within 20. 
  • MA.K.NSO.3.1 Explore addition of two whole numbers from 0 to 10, and related subtraction facts. 
  • MA.K.NSO.3.2 Add two one-digit whole numbers with sums from 0 to 10 and subtract using related facts with procedural reliability. 
  • MA.K.AR.1.3 Solve addition and subtraction real-world problems using objects, drawings, or equations to represent the problem. 

Key Concepts:

  • Fluency: Count to 100 by ones and tens
  • Put Together (Total Unknown Problems)
  • Put Together (Both Addends Unknown Problems)
