Interactive Math Activity - Estimating Lengths with Standard Units

Students will practice estimating lengths with standard units in this online math game geared toward third grade. Your students will choose the best unit of measure for a given length and answer the multiple-choice question based on their best estimate. After working through this interactive math activity, your students will become more confident in their ability to estimate lengths with standard units.

Your class may face various challenges in this online math activity, but boredom won't be one of them! That's because the measurement concepts in this math lesson are presented in a fun, engaging format that includes a variety of question types. Students may be asked, "Which has a length of about 7 inches?" They must choose from a hiking trail, a toothbrush, and a baseball bat. Or they may be given a word problem like this one: "Juliet's mother bought fabric to sew her costume for the school play. What is the best estimate for the length of the fabric?" Students will choose between about 2 yards and about 2 inches. Or students may be asked, "Choose the best unit of measure for the length of a backyard." They will choose between miles and yards. If children get stuck on a math question, they can opt to use the question hint, which will provide a helpful directive, such as "For shorter lengths, measure in inches and feet. For longer lengths, measure in yards and miles." When students answer a question incorrectly, a detailed explanation page will show them how to obtain the correct answer with an easy-to-follow explanation.

I Know It math lessons, including this third-grade measurement activity, are equipped with several handy features that help students make the most of each math practice session. A progress-tracker in the upper-right corner of the practice screen shows students how many questions they have answered in the lesson so far, and a score-tracker lets students see how many points they have earned in the lesson. The speaker icon in the upper-left corner of the practice screen indicates the read-aloud feature. Students can click the button and the question will be read to them in a clear voice. This is a great option for ESL/ELL students and students who are auditory processors!
