## Interactive Math Lesson - Reading and Writing Numbers up to 99

Here is a fun, engaging math practice activity that helps children with reading and writing numbers up to 99. This second-grade math lesson teaches important place value concepts, such as reading and writing numbers using base-ten numerals, number names, and expanded form. When children practice place value with this fun online math game, they will gain understanding and confidence in basic math skills.

Students will answer a variety of place value-related questions in this interactive math game from iKnowIt.com. Children may be given a set of place value blocks accompanied by the question, "What number is shown?" Or students may be given a number in written form with the directions, "Fill in the number that matches the word form." Or students may be asked to choose the word form that matches the number. If students get stuck on a question, they can click on the "Hint" button. They will be shown a pictorial clue that will help them solve the problem without giving away the right answer. When students answer a question incorrectly, a detailed explanation page will show them the correct answer with an easy-to-follow explanation, helping children to learn from mistakes along the way.

This second-grade place value activity is equipped with several handy features that help students make the most of their math practice session. For example, a speaker icon in the upper-left corner of the practice screen indicates the read-aloud feature; students can click the button to have the question read out loud to them in a clear voice. This is a great resource for ESL/ELL students and children who excel with auditory learning. On the opposite side of the practice screen, a progress-tracker tool shows students how many questions they have answered in the lesson so far. A score-tracker beneath that lets students see how many points they have earned for correct responses. Each math practice activity on iKnowIt.com is designed with your students' success in mind!
