In this lesson, students will use perceptual subitizing* as an efficient method for determining "how many". Through experiences, students will subitize sets within five.

*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 connect the oral number word and numeral to sets of objects counted. As they rote count, students will understand the concept that each successive number includes all the previous numbers (cardinality).

In this lesson, students will identify whether a quantity of objects in one group is greater than, less than or equal to a quantity of objects in another group. Students will use one-to-one correspondence (or other counting strategies) to answer the question: How many are in one group?

In this lesson, students compare sets and make equal sets. The lesson should be facilitated at the beginning of a unit on comparing sets once students have been exposed to comparison vocabulary (more, less, greater, fewer).

Lesson may be repeated with amounts closer in range, making it trickier to compare (i.e., 8 & 10).

In this lesson, students will identify how many manipulatives are in a given arrangement without counting each individual object (focus on 1-5). Students will understand the relationship between numbers and quantities, and will explain this relationship as they determine "how many" are in a set.

Note: Perceptual subitizing means to instantly recognize "how many" in 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.
