This week in math, our focus has been on rounding decimals to any place using place value understanding and vertical number lines. We began with renaming decimals using various units to strengthen students understanding of place value.
1.5 = _______ tenths (we know that there are 10 tenths in 1 whole so 1.5 is equal to 15 tenths)
1.5 = 15 tenths
2.5 = 25 tenths
12.5 = 125 tenths
Below is how we are decomposing numbers on the place value chart, and then plotting them on the vertical number line.
