This Decimal Rounding Sort
includes 12 unique games sets that will quickly build fluency for rounding decimals to the nearest tenth, nearest hundredth, and nearest whole number.
Each student is given a unique game mat and a deck of 16 decimal cards. The mat indicates what place students should be round the number and students sort the numbers into 4 buckets. The repetitive nature of the game will build mastery in a quick and exciting way.
For example, the game mat might say "Round to the nearest hundredth" and students would receive cards like 4.77934 and 4.791 and have to decide which bucket to place each number in (4.78 or 4.79). The decimal numbers intentionally have a variety of places (from tenths place to ten-thousandths place) to keep reinforcing the idea that when rounding, one must find the needed place and then use the place immediately to the right to determine what it rounds to. Each set is equally split between numbers that round up and numbers that round down.
