Adding+and+Subtracting+Fractions

This is a set of cards I use to "preassess" where my students are with adding fractions at the beginning of this unit. I cut them out and give one set to each pair of students. Basically the directions are to:
 * solve the problems
 * write a general explanation about how to solve fraction addition problems
 * rank the problems in order from easiest to most difficult- explain why one is easier than the next
 * make up an additional example similar to those given


 * [[file:All about Fractions - subtraction differentiation.doc]]Same as the above, except for six subtraction problems.

This activity is for exploring mixed numbers and improper fractions with pattern blocks - This is an exploratory activity with the new fraction pattern blocks...adding fractions and mixed numbers


 * [[file:Fraction pattern blocks 2011.docx]]added a few extra problems to the activity above
 * [[file:Pattern Block Clip Art.docx]]- a pattern block template for making your own pattern block activity.

This is the powerpoint I use to teach subtracting mixed number. I use an example of needing exact change to buy something that costs 3 dollars and 3 quarters when I have five dollars and 1 quarter and then show how this relates to fractions.

This is a model we came up with to try this year...in the interest of having students come up with a visual representation of the word problem, then the expression, an estimate, a solution, and then solve in the context of the problem. This document has two addition word problems, two subtraction word problems, and a blank model....
