A good maths game where players fly a spaceship through a time tunnel, collecting fuel as you go. Set a clock to the correct time to go to the next stage. There are four different levels of time-telling ability.

(abstract only, full text requires subscription or purchase) "We analyze the logs of an online mathematics game tournament, played simultaneously by thousands of students. Nearly 10,000 students, coming from 356 schools from all regions in Chile, registered to the fourth tournament instance. The children play in teams of 12 students from the same class, and send their personal bets to a central server every 2 minutes. Each competition lasts about one clock hour and takes place within school hours. Students are pre-registered and trained by their school teacher. The teacher is responsible for reviewing curriculum contents useful for improving performance at the game and coaches students participating in trial tournaments taking place a few weeks before the national tournament. All bets are recorded in a database that enables us to analyze later the sequence of bets made by each student. Using cluster analysis with this information, we have identified three types of players, each with a well-defined strategy. "
SUPERB! Place the numbers on the number line. Loads of levels. Negative numbers and decimals. Play against the clock for a score. My class's favourite warm up, useful throughout school from year 3 to year 6.
A Dustbin game is great for helping students to organise ideas into categories.
Students or teachers can create up to four categories of factors. The game created by ClassTools.net then involves students dragging and dropping each factor into its correct category as quickly as possible in a "race against the clock"!
