# What Is 100?

\$1.95

In the lesson What Is 100?, students will learn how to show that 100 can be represented by 10 groups of 10. The lesson provides teachers with a number of methods, such as one hundreds charts or place value cubes, to illustrate this concept. The lesson itself contains several math tools to help along the way.

Additionally, students will learn about place values up to the hundreds place. They will also learn the meaning of zeros in relation to place values. Using activity and practice sheets, students can demonstrate their comprehension. By the end of the lesson, they will be able to determine the place values of numbers up to three digits.

## What our What is 100? lesson plan includes

Lesson Objectives and Overview: What Is 100? teaches children how to represent the number 100 by 10 groups of 10. The lesson will present a few different ways (through division, multiplication, and addition) to show how. Additionally, it contains several math tools to make it easier for students to understand the idea. These tools include a place value chart, a hundreds chart, and base ten blocks.

One reason this concept is important is that many future math strategies will build on the idea of grouping. This lesson describes the concept of place values, emphasizing the idea the ten groups of ten make one hundred. For instance, a chart within the lesson represents the number 100 by hundreds, tens, and ones. It explains how the place value of zeros in 100 means there are no tens or ones. Using the chart, students can break down the number 100 by hundreds, tens, and ones. In the first row, for example, there is nothing in the hundreds and tens columns. However, the ones column shows the number 100. This means there are 100 ones in one hundred.

This lesson contains several worksheets to aid students in their learning. After learning about the concept, you can distribute the worksheets to the students. You can find the answer keys to these various activities at the end of the lesson.

#### WHAT IS 100? ACTIVITY

In the activity that follows the content pages, students will answer how many 10s are in 100. Through whichever means they choose, they will have to prove their answer. Some suggestions include using base ten blocks, drawings, or equations. After that, students will then organize their answer on chart paper. Finally, they will share their answers with the class and describe the strategy they used.

#### MATH JOURNAL

The Math Journal page asks students to answer a couple questions about place value: What does the 1 in 100 represent? What do the zeros represent? The will be expected to explain their answers.

#### PLACE VALUES PRACTICE WORKSHEET

The practice page will help students demonstrate their understanding even further. First the students will match the individual values of three-digit numbers to the correct place value column (hundreds, tens, ones). There will be hints in the chart to help them. They will then answer six questions based on the information in the chart.

#### PLACE VALUES HOMEWORK ASSIGNMENT

The homework will reflect their comprehension similar to the practice worksheet. Without hints, the students will place values of given numbers in the correct place value column. Afterward, they will again answer questions to demonstrate their knowledge.

At the end, the lesson provides answer keys for the Activity, Math Journal, Practice, and Homework sheets.
