Estimating Lengths (Inches)

Students will practice estimating lengths in inches in this interactive math practice activity geared toward second grade. Math questions are presented in multiple-choice format so students must decide the best estimate for the object(s) in question. After completing this online math game, your students will be more confident in their ability to estimate lengths in inches.

Children will be asked a variety of engaging measurement questions in this online math practice activity. For example, they may be shown two objects such as a lemon and a carrot with an accompanying question: "Which object is about 9 inches long?" Or they may be required to compare the lengths of two objects side-by-side: "The paperclip is 2 inches long. What is the best estimate for the length of the pencil?" Or children may have to compare an object against a ruler: "Is the paperclip closer to 2 inches or 3 inches?" As students work through the math activity, they will have the opportunity to use the "Hint" button if they get stuck on a question. The hint will display a detailed picture to help children visualize the measurement concept being tested. When students answer a question incorrectly, a detailed explanation page will show them the correct answer and provide an easy-to-understand explanation. Students will learn from past mistakes as they progress through the lesson.

This interactive math activity is equipped with several handy features that help students make the most of their math practice sessions. A speaker icon indicates the read-aloud feature; when this button is clicked, the question will be read out loud in a clear voice. This is a great option for ESL/ELL students as well as students who are auditory processors. A progress-tracker shows students how many questions they have answered so far in the math lesson out of the total number of questions. A score-tracker lets students know how many points they have achieved so far in the lesson. These tools are designed to help children feel confident in achieving their math goals during practice time.
