Texas Instruments - Middle Grades

In the first problem, students will use a pie chart to help them determine whether to round a fraction to the nearest whole number or nearest half. If section 1 takes up most or none of the circle students will round to the nearest whole, and if the section 1 takes up only half of the circle, they will round to the nearest half.
In Problems 2 and 3, students will use the rounding skills they learned in the previous problem to estimate sums and differences.
As an extension or homework assignment, students can use a program to generate random fractions to use in addition and subtraction problems. Again, they will use rounding to estimate solutions before finding exact answers.
