Rounding Roller Coaster is a hands-on way to help elementary students learn the fundamental skill of how to round numbers. Rounding is part of state testing in 49 out of 50 states; however, it is a math concept that can be difficult for students to master. When students learn to round numbers, they first need to understand there are only two possible choices, then use their number sense to determine the correct answer. Rounding Roller Coaster makes the process of learning to round purposeful and memorable—students attach the colorful train cars in numerical order to the roller coaster frame; send their roller coaster cars to the correct collection trays; then round up or down accurately.

Created by a public school teacher, Rounding Roller Coaster is designed to be fun and engaging for students, and easy for classroom teachers to use. Rounding Roller Coaster uses easy-to-assemble snap-fit attachments that are fast and efficient to set up, leaving more time to work directly with students. No other product on the market offers a hands-on introduction to rounding, and Rounding Roller Coaster is a proven concept that fills the need for teachers looking to meet state math standards.
