In 1806, Terry received a contract to build 4,000 clocks in three years. He eventually created templates for these machines that allowed for the precise production of standardized parts, meaning they no longer needed a master clockmaker for finishing. In the beginning of the 19 th century, Terry purchased a water powered grain mill he adapted to cut wooden clock parts. Realizing the potential to increase efficiency by making many of the same parts, Terry sought out ways to make the parts faster. These exchangeable parts meant that new clocks did not need every part fabricated. Terry would eventually bring mass production to the craft of clock making and revolutionize the craft, not just for the United States, but the world.Īs an apprentice to Daniel Burnap, Terry learned about producing standardized and exchangeable parts out of wood to speed up clock production. At the time, clock making was extremely labor intensive and master clockmakers were lucky to produce more than a few clocks a year. Terry was born in South Windsor, CT in 1772. No one had a bigger impact on the craft than Eli Terry.

Although it comes with a deck and you can download others from our website, it was really designed to encourage teachers and students make and share their own matching game decks to capture their understanding and challenge others. MathTappers: MultiMatch-a matching app that challenges learners to match sets of cards placed on the table. Please check out all of our MathTappers apps (links found at ): We have designed MathTappers apps to support students in learning mathematics by providing relevant visual models, focused content linked games and helpful suggestions for parents and educators. The designers of the MathTappers Apps are math educators and researchers seeking to create simple games that will help learners to make sense of mathematics one concept at a time. It may also be helpful for non-native English speakers to learn the clock words.ĭesign: Tim Pelton & Leslee Francis Pelton 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. The ‘Number-Words’ version represents the words that might typically be spoken by someone who has mastered the Analog clock when describing the time. It may be easier for children to ‘read’ but often this ability comes without understanding.
This can be used to help children understand the nature of the hour hand, the number of minutes in an hour and the secondary nature of the minute hand (note that early clocks did not have a minute hand and sundials never will)įor 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. 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. 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). Players may choose the types of clocks that are presented on the screen and which clock will be set during the game (top or bottom). 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, analog, and number-word clocks. Children need explicit opportunities to work with clocks to discover how the system we use to tell and record time works. 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. It is something that we measure but it is also something that we cannot touch or feel. Time is a topic that many children struggle to understand. MathTappers: ClockMaster is a game designed to help children make the connection between hours and minutes and to help them become fluent in both reading and setting time on digital clocks, number-word clocks, and analog clocks.
