### Overview

This whole group activity will allow students to notice patterns as they orally count by ones and tens up to 100.

Mathematics (2019) Grade(s): KG

### MA19.K.1

Count forward orally from 0 to 100 by ones and by tens. Count backward orally from 10 to 0 by ones.

• how to count by ones and tens orally. This includes counting forward and counting backward.

### Skills

Students are able to:
• orally count forward.
• orally count backward.

### Understanding

Students understand that:
• Counting from 0 to 100 is a sequence.

### Phase

Before/Engage
Learning Objectives

### Learning Objectives

Students will be able to count to 100 by ones and tens and count backward from 10 to 0.

### Activity Details

1. The students will gather and sit in a circle. The teacher will explain to the students they will be practicing their counting skills by orally counting from 0 to 100 by ones and/or tens.
2. The teacher will choose a student to begin the activity and show the students they are moving clockwise and to the left as they count. This number sense routine can be used over a series of days to allow time for ample practice.
3. After the students practice counting forward, they will repeat the activity counting backward from ten to zero.
4. The teacher will ask the following types of questions:
• If we count around the circle starting at 0, what number do you think we will stop on?
• If we count around the circle starting at 10, what number do you think Savannah will say?
• If we start at the number 45, what number will Sawyer say?
• Was it easier to count forward or backward? Why?
• What patterns did you notice as we were counting?

Assessment Strategies

### Assessment Strategies

The teacher will observe the students' responses to determine students' understanding of the concept and skills. The teacher can use the following guidelines to ensure students meet the learning objective based on the essential questions.

Check that the student:

1. can correctly count forward without skipping a number.
2. can correctly count forward without repeating a number.
3. can correctly count forward fluidly and without hesitation.
4. can correctly count backward from ten to zero.

### Variation Tips

The questioning can be extended and enriched as the students master the standard.

### Background / Preparation

The teacher will need to develop the essential questions before beginning the activity.
