MathTappers: ClockMaster - a math game to help children learn to read clocks

By HeavyLifters Network Ltd.

Open iTunes to buy and download apps.


MathTappers: Clockmaster is a game to help children make the connection between hours and minutes and to help them become fluent in both reading and setting time on digital and analog clocks.
Special offer! Free until September 30, 2011.

Time is a topic that many children struggle to understand. It is something that we measure but it is also something that we cannot touch or feel. Although some aspects of time may be mastered incidentally as children experience circumstances where elapsed time and time of day are used to compare or plan, this type understanding is generally incomplete. Children need explicit opportunities to work with clocks to discover how the system we use to tell and record time works.

MathTappers: Clockmaster offers both a practice mode to support exploration and tutoring activities and a game mode to help players to become fluent in both reading and setting time on digital and analog clocks.

Players may choose both the type of clocks that are presented and which clock will be set during the game (top or bottom).

For the top clock there are two modes:
The ‘Normal Analog’ version is a traditional clock face with minute and hour hands while the ‘Broken’ clock shows only the hour hand (with the minute hand broken off). When the minute hand is missing the child can focus on the relationship between the hour hand and the hours and minutes shown on the digital clock. This is a very useful tool for helping children understand the nature of the hour hand, the number of minutes in an hour and the secondary nature of the minute hand (indeed early clocks did not have a minute hand and sundials never will)

For the bottom clock there are also two modes: The ‘Digital’ version is a traditional digital clock – a representation found on most electronic devices and computers. It may be easier for children to ‘read’ but often this ability comes without understanding. The ‘Words’ version represents the words that might typically be spoken by someone who has mastered the Analog clock when describing the time. It is expected that this second mode will be most helpful after players have mastered the relationship between the Analog clock and the Digital clock. It may also be helpful for non-native English speakers to learn the clock words.

Clock Free app - great

Really good. My 6 yr is hooked on and it is helping her get used to clock and how to tell time quick. I am giving 5 stars as it is free, but I would have liked to see an option where kid gets questions, and answers are timed for quick response (multiple choice), and there is a score. Generally scoring provides another level of challenge for my daughter - just like doing better at games. Great free product.

Great app!

Can't wait to use this with my students that struggle with telling time. Love the different ways you can set the levels & clock faces. The "broken" mode is not explained in the directions at all, so that took some time to figure out, but I like the added level of challenge it presents to students that know how to tell time. Thanks for fantastic free app!


I visited with one of the developers of this app at the ISTE conference today. I downloaded it on the spot, and have a place in my lesson plans for using this app on an IPAD for the entire school year. If my students have access to an IPOD touch, or I-Phone at home -I'll definitely have them download this app!
