Week 7 Virtual Manipulative: Diffy

This manipulative is found under Number & Operations (Grades 6 – 8). Diffy is designed to help students practice subtraction. Students have to find the differences of the given number. If their answer is correct they continue till they are done filling in all the answers. If they type in the wrong answer they will not be able to continue on to the smaller squares. Students are able to choose which kind of numbers to use for the difference. Students can pick from whole numbers, integers, fractions, decimals and money. This is a good manipulative to use with students once subtraction has been introduced with one of the five number options.

Week 7 Lesson Plan: From A to Z (Geoboard)

From A to Z is a two player game. Students take turn making secret letters on their Geoboardes and describing them to the other player who tries to make the letters from the information given. In this activity students have the opportunity to identify attributes of lines and communicate specific information. This activity provides students with a way to link mathematics to another important K-2 curriculum area such as language arts.
