Our MathTappers: Carbon Choices app is designed to help users (students/parents/teachers) become more aware of the amount of C02 equivalent (C02e) pollution introduced by their lifestyle choices. Users begin by tracking/estimating their consumption over a week (showers, entertainment, travel and food). Their impact is then assessed in terms of annualized kg of CO2e generated.

Climate change, greenhouse gases (GHG), C02e, etc. are fuzzy terms to most of us. We know that they describe a problem, but we can’t easily define them or interpret the magnitude of the numbers that we hear. This app is intended to support students, parents and teachers in building a sound understanding of the numeric values associated with these terms. MathTappers: Carbon Choices takes everyday activities (i.e., bathing, eating, transportation, entertainment) and helps students to make the connection between their everyday choices (e.g., minutes in the shower, km travelled by car, type of food consumed, etc.) and the kg of C02e that will be emitted if they repeat those choices over a year.

When using this app to estimate personal carbon footprints (everyday things that we can really easily change) users will typically see values in the range 1000-4000 kg of C02e each year By understanding how many kg of C02e they are responsible for through their personal actions and choices – students, parents and teachers will find the issue of climate change and greenhouse gas to be less abstract and easier to discuss and to address. (Note: the average North American lifestyle is responsible for the generation of approximately 20 tonnes of GHG each year).

This app is specifically designed to support the recording of activities, contexts and choices common to youth. Specifically users can describe their:

(a) shower in terms of flow rate, input temperature, output temperature and duration

(b) food choices in terms of consumption of high, medium and low impact foods

(c) transportation in terms of vehicle fuel economy, vehicle fuel type and the number of kilometers driven at their request or on their behalf

(d) entertainment in terms of system wattage consumed when operated and time used and discover the kg of CO2e that their choices would generate over a year.

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. 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.

Please check out all of our MathTappers apps (links found at MathTappers.com):

MathTappers: MultiMatch--a matching app that challenges learners to match sets of cards placed on the table. 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: Clock Master--learn to tell time

MathTappers: Estimate Fractions--make sense of fraction sums and differences

MathTappers: Find Sums--learn basic facts for addition and subtraction

MathTappers: Multiples--learn basic facts for multiplication and division

MathTappers: Equivalents--equivalent fractions, decimals and percents
