Find Missing Exponent or Base


Find Missing Exponent or Base introduces students to how to find missing exponents and bases. Students will learn how to make a chart to help them accomplish this task. The chart allows them to see how exponents work. Students will learn how to find the base as well by thinking backward.

The “Options for Lesson” section offers several suggestions that you could incorporate into your lesson. One option is to use larger numbers to challenge more advanced students. Another options is to have students create posters of whole numbers and their list of exponents. These could be hung on the wall for reference.

What our Find Missing Exponent or Base lesson plan includes

Lesson Objectives and Overview: Find Missing Exponent or Base teaches students how to find a missing exponent or base value. Students will learn how to solve for these values in equations involving numbers under 12. They will be able to practice this skill with several examples.

There are two pages of content in this lesson. The first page explains what to do if an exponent is missing. It presents the idea of using a chart to figure it out. The second page builds on the concept and presents another example. It also introduces the power of 10 concept. Knowing this concept will help students very much when they have 10 as a base number in an equation.


For the activity, students will need to cut out all the boxes on the table. The worksheet presents a table with 10 rows of numbers that are all factors of 10. The first column has the numbers in word form. The second column shows them as numerals. The third columns displays the exponent form. However, the numbers in each column are out of order. Students must paste the three columns in ascending order. Each row must represent the same number.


The practice worksheet requires students to find the missing exponent. There are nine questions on the worksheet. There are also empty boxes that the students can use to make a chart.


Similar to the practice worksheet, students must find the missing exponent. There are six questions to solve. Students can use the empty boxes under each question to create a chart that will help them solve the problems. In addition, they will also find the missing base for three questions.


The quiz worksheet has a few sections. The first requires students to describe a base and exponent and label the corresponding arrows. Then they will find a missing exponent. Finally, they will find a missing base.
