Your students will become place value pros when they practice basic place value up to 99 in this interactive math lesson. Students will practice place value concepts such as identifying the number represented by the place value blocks and how many tens and ones are in a given number.

Math problems are presented in a variety of formats in this second grade place value lesson. Students may be asked which number is shown by the place value blocks. Students may be asked how many tens and how many ones are in the number. They may be asked to choose the number that represents the word form. They may also be given a math fact to solve, such as 60 + 5 = [blank].

If students need a little extra help solving a math problem in this place value practice session, they can click on the hint button in the lower-left corner of their screen. They will be shown a pictorial clue, such as a table in which place value blocks are sorted into tens and ones. If students answer a math problem incorrectly, they will be shown a detailed explanation page complete with a custom graphic that illustrates how to solve the place value problem correctly. Students can move onto the next question having learned from their mistakes.

'I Know It' is designed to help elementary-aged students become confident and proficient in basic math skills, including place value up to ninety-nine. Our website has a cheerful, kid-friendly design and layout. 'I Know It' is easy to navigate and has large icons, colorful headings, cute animated characters, and a motivating award system to help children make the most out of their math practice time.

Teachers appreciate the wide variety of math topics covered in our online math program. All of our math lessons include several features that help students excel in their math practice. For example, a progress-tracker in the upper-right corner of the practice screen shows children how many questions they have answered in the lesson so far. A score-tracker beneath that shows them how many math problems they have solved correctly so far. Plus, a speaker icon in the upper-left corner of the screen indicates the read-aloud feature. Children can click on this button and have the question read out loud to them in a clear voice. What a great option for ESL/ELL students and students who prefer auditory learning!
