## Interactive Math Lesson - Estimating Lengths in Centimeters

Put your students' measurement skills to the test with a fun, interactive math game from iKnowIt.com. In this digital math activity, children will practice estimating lengths in centimeters. Here are the learning objectives of this second grade measurement activity:

• Estimate the length in centimeters of a given object.
• Decide which length in centimeters is the better estimate for a given object.
• Determine about how long in centimeters a given object is.
• Determine which object is closer to the given length in centimeters.

As students work through this measurement lesson, they will answer a variety of multiple-choice questions.

Children will have plenty of helpful tools available to them in this measurement math practice session. For example, when students get stuck on a math problem, they can click on the "Hint" button. They will be shown a written or pictorial clue that will point them in the right direction without giving away the answer. When students answer a question incorrectly, a detailed explanation page will appear on the screen, showing the correct answer accompanied by an easy-to-understand explanation.

Here are a few other built-in math lesson features that will help students make the most of their math practice session:

• A progress-tracker in the upper-right corner of the practice screen shows students how many questions they have answered out of the total number of questions in the math activity.
• A score-tracker lets students see how many points they have earned for correct responses.
• The speaker icon in the upper-left corner of the practice screen indicates the read-aloud feature. Students can click the button to hear the question read out loud to them in a clear voice. This is a great option for ESL/ELL students and children who are auditory processors.

All of these features and tools were designed by the I Know It team to help your students achieve more in their math practice.
