Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Virtual Manipulatives
This interactive Flash applet supports the exploration of numbers to 100 by simulating a 100-bead string. A teacher or child can move all or some beads to the left or right to add and subtract. The controls allow users to move beads individually or 10 at a time to model different counting and calculation strategies. Users can hide or show the numbers represented by the beads. This applet lends itself well to use on an interactive white board. A PDF guide to this collection of teaching applets is cataloged separately.
Type: Virtual Manipulative

A number of how many they can net is displayed in the top right, and they will use the mouse to net that amount into the tank before releasing them for the next round. When the timer is up, another screen comes up with the number of octopuses saved represented in rows of ten. Finally, students will be asked to input on a number line how many they successfully saved.

Educational Game
This site features an educational game of chance set to the familiar nursery rhyme "The Incey Wincey Spider". It helps students learn to move along a track on either side of a central point, as a precursor to working on a number line. The game is played with two people who roll a die to move either up or down a vertical waterspout. The game can be played with the applet or on paper. All you need is two dice (number generators).
