Students who need practice performing subtraction of a single digit can use this short worksheet that provides immediate feedback. It is self-checking. While having fun decoding a secret message (and... More > getting immediate, satisfying feedback) young students will complete ten subtraction problems. (A secondary goal of the worksheet for some students is for them to use inductive reasoning to notice that in all of the problems the second term is half of the first, so the difference will always be equal to the subtracted term.) Similar PUZZLE MATH worksheets and books on subtraction and later math topics are available at www.lulu.com/roxlulu, including, "PUZZLE MATH: Simple Subtraction Practice", "PUZZLE MATH: Adding, Subtracting, Multiplying, and Dividing Fractions", and "PUZZLE MATH: Trigonometry and Logarithms".< Less
These two worksheets are on solving proportions. One has students solve proportions equations, and the other has students set up and solve proportions equations to solve word problems. The secret...
