I have created hands on time tools to help your students understand adding and subtracting time. This is great to use in small group, intervention, and for introducing this tek. The tools include Number lines in intervals of 5, 10, 15, and 30 minutes, and time pieces that fit on each number line that are the following sizes, 5, 10, 15, 30, 1 hour. You use the time pieces and place them on the number line to help you solve your problems. There are no word problems included yet in this product. Just the tools you need to help students get a hands on feel of adding and subtracting time on a number line.Below is how i use these in class.
How I use this Activity: I use this activity as a hands on way to introduce adding and subtracting time. We get out our white boards and our time number lines and pieces. We will first decide on an activity. Example: Going to the park. I will then ask the class to decide on 3 activities we can do at the park. Example: play fetch, rock climb, and play on the monkey bars. We will then make a table to portray this info. The kids will then give me an amount of time for each activity. We will then make a fourth column for the total amount of time. If it is over an hour we will subtract 60 minutes till we have the amount of time written as hour and minutes. I will then give the students a start or end time. We will then pick either the 5, 10, 15 or 30 minute number line and act out each activity by building the amount of time for each activity with the time pieces. WE will then label our number line with jumps either forward or backward (depending on whether we knew the start or end time. We will then practice solving the problems using a clock. I am also going to use the time pieces this year to make strip diagrams about time. We never know how the staar test will test it. I know this activity helped my students be able to add and subtract time on the number line and it also helped them memorize how the minutes of an hour can be broken up.
The number lines are to be printed on card stock. You will print one half of the number line on one page and the other half on the the other page. You will then have to line up the pages and tape them together before or after you laminate them. You will need to line up the line on the begin and end of the two pages.
