Fri 14th - Using Rounding to find approximate solutions to calculations

LEARNING OBJECTIVE: To develop Rounding and Estimating skills.
SUCCESS CRITERIA: You will be able to use rounding to estimate the solution to problems 

ENGAGEMENT ACTIVITY:

Copy and complete the following table:

To Nearest	10000	1000	100	10
45,678	50,000	46,000	45,700	45680
30,983	30,000	31,000	31,000	30,980
980,981	980,000	981,000	981,000	980,990

LESSON: Look at examples of rounding to estimate the answers to calculations:

Use rounding to 1sf to find approximate answers to solutions
