Lesson objective: Understand that when we find one more, it is the next number name we say when we're counting by ones.

Students bring prior knowledge of one more using pictures as a support. This prior knowledge is extended to counting to find one more as students use the concept of counting by ones to find the next number name. A conceptual challenge students may encounter is understanding what the word more means and how it applies to numbers. 

The concept is developed through work with a number path, which gives students a visual reminder of how to count by ones and promotes fluency in adding one more to a number easily.

This work helps students deepen their understanding of numbers because as students count by ones they will find that each number name they say is one more than the number before it.

Students engage in Mathematical Practice 1 (Make sense of problems and persevere in solving them) as they apply their prior knowledge of counting and number order to different situations where finding one more is needed in order to problem solve and compute.

Key vocabulary:

  • number path
  • before
  • number name
  • one more

Special materials needed:

  • number paths for all students
  • counters if needed for support
