Use these to teach and work with numbers 1-10, and combine then to form numbers 11-20, or adding and subtracting. Each number bar is fixed, and always the same color, so students only have to focus on one variable, the quantity! Students usually begin automatically subitizing, or associate the quantity with the color, without counting each time. Also great for decomposing numbers and seeing which quantity is greater!
