## Interactive Math Lesson - Place Value with Hundreds, Tens, and Ones

Help little ones understand place value basics with this interactive math lesson from iKnowIt.com. In this online math game geared toward a first-grade ability level, children will practice place value with hundreds, tens, and ones. Students will fill in the blank and answer multiple-choice questions as they determine important place value concepts, such as the value of the underlined digit and the numerical value of the written form of a number. Upon completion of this interactive math activity, your little learners will have gained mastery and confidence in basic place value skills.

Here are some examples of the questions students may be asked in this first-grade place value game: "What number is shown?" Students must count the place value blocks and choose the correct response. "The number 957 has how many hundreds, how many tens, and how many ones?" Students must fill in the blank with the right answer. "What is the value of the underlined digit: 724" Students will choose from "200," "20," and "2." If students need a little extra help solving a math problem, they can always click on the "Hint" button. They will be shown a helpful written or pictorial clue that will get them thinking about the question in a new way. When students answer a question incorrectly, a detailed explanation page will show them the correct answer with an easy-to-understand explanation, helping them to learn from mistakes as they move through the lesson. Your students will be engaged and challenged by the variety of question types and the tools available to them as they learn!

Additional features are available in all math activities on I Know It to help students make the most of their math practice sessions. For example, 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 lesson. A score-tracker lets students see how many points they have earned for correct answers so far. A 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 out loud to them in a clear voice. This is a wonderful option for ESL/ELL students and children who prefer auditory learning. All of these features are designed with your students' success in mind!
