The central theme is that of a backyard fair. Blue helps the child complete various activities, which are rewarded in Blue Dollars that may be exchanged for prizes in the prize tent. The educational concepts being delivered include pattern recognition, weight and measurement, simple addition and subtraction, sorting and classifying, prediction and estimation. The animations are charming and simple, with bold, bright backgrounds. And the user interface accurately reflects the needs of the target audience.
Directions are clear, cursors and navigation icons are large and easy to find.
Instructions may be repeated simply by moving the cursor over the animation that first gave them. Not all the activities are slam-dunk easy. In one card game against a teddy bear, the idea was to match either the shape or the number until you matched out all five cards dealt you. If you had no matches in your hand and less than five cards, you had to draw from the pack. I thought it sounded simple.
