This interactive SMARTboard lesson is great way to introduce, practice, or review the use of a number line. The lesson increases in difficulty as you continue to use the number line. Use your finger or a SMART pen and mark the starting point. Either count forward or count back to find your answer. As you move through the lesson, hints and numbers become less so the student has to problem solve themself. The second half of the lesson is designed as a game if teacher decides to use that way. Each student answers each question and they keep track of their own score. Each problem has a point value. The last slide offers a blank number line for you to place any numbers you like on the number line and ask your own questions. Erase the numbers and use over and over. All slides are self checking. Must have at least SMART Notebook 11 to use. Great for grades 3-6 depending on the level of support you give.
