1. Data Around Us – (number sense)

Estimation and rounding
Need some help learning how to round and estimate?  This website will tell you how. The "workout" section lets your practice your skill.
http://www.math.com/school/subject1/lessons/S1U1L3GL.html

Challenge yourself to a rounding game on Funbrain.com. It includes both whole numbers and decimals.  Which level did you try?

2. Variables and Patterns

Patterns and rules
Here is a page that has lots of links.  Each of the links examines a  cool pattern or set of patterns.  Check it out.  See if the patterns can be measured or predicted. Can you discover any rules for these patterns? (Some of the links don't work. Check the Interactive Sky Charts and the M.C. Escher Gallery for some neat patterns.)
