I was looking for hands on activities for 4th to 6th graders to practice with decimals. I used the beams and large beams with 10 holes in one line to represent choices for each place value. One board can be set up with each GO kit. The advantage of using the GO kit for this practice is that the correct order of the quantities is REALLY obvious with the 3D visual!
Comparing & Ordering Decimals (Rational Numbers for 6th Graders): See photos below of setup and examples. The white beams & large beams are pinned to the board with red pins in 3 groupings to allow ordering 3 different quantities. An orange standoff is used for the decimal point for each grouping. The values at the top and bottom of each place value are shown for the ones, tenths, and hundredths. This activity can be played as a game with 2 - 4 students. The 1st student uses green pins and yellow standoffs to pick 3 numbers using all 3 place values in each grouping. If a digit is picked in the location of a red pin, it can be changed out for a green pin. Other student(s) determine the order of the quantities from least to greatest correctly, together or separately, to get the point. If they don’t, the 1st student gets the point. A timer could be used. The number of groupings could be increased or decreased to alter the challenge level. The place values included could be adjusted to alter the challenge level.
