How I Use It
Number Line by Math Learning Center is a free app provided to be used in conjunction with their curriculum, Bridges 2. However, it's a great app for use with any math program. The app is a number line that students can use to manipulate numbers, solve problems, and illustrate their mathematical thinking. The Number Line app allows for a variety of numbering options. Whole numbers, fractions, and decimals can be numbered, as well as the option for custom numbering. Spacing of ticks can be adjusted, as well. Students can move to locations on the number line quickly. Solving problems using jumps can be done with a jump stamp, both forward and backward, or by using the drawing tool. A keypad is included for creating expressions and equations. The Number Line app has been a very useful app in my classroom. My second and third grade students have used number lines frequently to solve problems (Bridges 2 is our district's math curriculum). The Number Line app provided a great model of number lines for drawing and labeling them, and it was useful in illustrating the use of benchmark numbers for struggling students. Of course, students can draw number lines, but this app provided an additional, very engaging way to make number lines. It is also useful for parents. I found that when I showed parents how to use this app, the purpose and method for using number lines became understandable. Lots of "a-ha" moments came from using this app.
Number Line by Math Learning Center is a very useful teaching tool. It works well in conjunction with student instruction in the use of number lines as a tool for addition, subtraction, or multiplication. I have found it to be helpful for parents, many of whom had ever used number lines as a tool for problem-solving, for them to understand student lessons and homework. Rather than drawing number lines on paper, Number Line by Math Learning Center provides a different, engaging way for students to use number lines to illustrate their math strategies.
