### Overview

In this final check, the students will connect counting to cardinality by indicating the number of objects in a set regardless of their arrangement or the order in which they were counted.

This activity results from the ALEX Resource Development Summit.

### MA19.K.4

Connect counting to cardinality using a variety of concrete objects.

## UP:MA19.K.4

### Vocabulary

• Cardinality
• One to one correspondence
• Hierarchical inclusion

### Knowledge

Students know:
• Use one to one correspondence when counting objects.
• how to rote count in consecutive order.

### Skills

Students are able to:
• count objects with one to one correspondence.
• Indicate the number of objects.
• Explain one more.

### Understanding

Students understand that:
• a number represents a quantity.

### Phase

After/Explain/Elaborate
Learning Objectives

### Learning Objectives

Students will understand the relationship between numbers and quantities while connecting counting to cardinality.

### Activity Details

Print off the Counting and Cardinality Assessment page and cut the representations of numbers 0-10 and place in individual cups or bowls for each student. Provide students with a sentence strip.

This assessment should be done individually at a small group table or with a small group spread out.

1. Say “Here is a cup of numbers. You will not use all of them. You may choose which ones you would like to use."
2. "Lay these numbers in order on the sentence strip the way that we count. You may choose which ones you want to use. You may use numerals, dice, and ten frames. You may choose."
3. "Now glue the numbers you chose in order on the sentence strip the way that we count."
4. "Tell me the numbers you glued down." TEACHER will record their response if there is an issue.
5. "Write your name on the back of the sentence strip."
6. Teacher will choose an extra dice or ten frame and ask “What number is this and how do you know?“ TEACHER will record their response.
Assessment Strategies

### Assessment Strategies

Collect student work at the conclusion of this activity to assess their knowledge of counting and cardinality. You can use the following guidelines to ensure students met the learning objective.

Check that the student:

1. glued the numbers 0-10 in correct sequential order.
2. glued the numbers starting left to right on the sentence strip.
3. wrote their name on the back of the sentence strip.
4. could tell you the extra number you held up and could explain how they knew it was that number. (using an extra 10 frame or dice)

### Variation Tips

Once your students have mastered gluing the numbers in sequential order from left to right on the sentence strip, ask them to illustrate one of the numerals they used and write an equation to match that numeral. (If the student used the numeral 9, ask them to illustrate 9 things and to write an equation that equals 9.)

### Background / Preparation

Make a copy of the Counting and Cardinality Assessment page (digital tool) for each student. Cut the pieces apart and put in individual cups or bowls so that each student will have a set of numerals, dice, and ten frames.  Each student will need a sentence strip and glue.
