This lesson should occur after students have experiences with perceptual subitizing*.
In this lesson, students use conceptual subitizing** as a flexible and efficient method for finding "how many".
*Perceptual subitizing: instantly recognizing "how many" in a set
**Conceptual subitizing: efficiently finding "how many" by recognizing and combining subgroups within a set.

In this lesson, students will identify the number of objects in a group as greater than, less than, or equal to the number of objects in another group, for numbers 1-5. Students will understand the relationship between number labels (such as "4" naming a collection of four) and quantities. They will understand that counting by ones increases the quantity by one more.

In this lesson, students use their understanding of word problems to sort problems based on type. The focus for students in this lesson shifts from solving word problems to analyzing word problem structures in order to group like problems. The purpose is to help students understand and visualize problems so they will know how to write equations that match and know what operation is needed to solve. This lesson focuses on sorting addition and subtraction word problems with a specific focus on Take Apart and Put Together types. The lesson, however, can be adjusted to use with any problem types you notice students need more experience with. You could also adjust the number size in the problems to use this lesson at different times in the year.
