MathTappers: Fraction Estimation is designed to help learners to build their intuitive understanding of fractions by helping them to relate fractions (both symbols and pictures) to the nearest half (e.g., 0, 1/2 1, 1 1/2, 2, etc.) and then to extend their understanding by challenging them to use fraction estimates in addition and subtraction problems. Learners should be able to master the challenges in this app before moving on to formal operations with fractions. We recommend that this app be used in conjunction with classroom or tutoring activities to support consolidation, mastery and fluency through a series of manageable challenges. The purpose of this app is to support learners as they are developing their understanding of fractions, fraction symbols and fraction operations by emphasizing sense-making through estimation and the use of visual models. Evidence suggests that if learners are taught formulas and procedures before they develop understanding, then they may not be motivated to spend the effort needed to make sense of what they are doing. We want to support sense-making before procedural mastery. This app is not intended to be mastered in one shot – rather levels should be assigned judiciously to support classroom learning activities. After introducing each fraction idea (fraction estimation, and estimation of sums and differences) in a classroom presentation, explanation or discussion this app may be used in small group and individual activities to support exploration, sense-making, consolidation and remediation. Design: Tim Pelton & Leslee Francis Pelton Programming: Mike Anderson, Joshua E. Smith & Garrett Reimer 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.

Verdict

Both are free to download. MathTappers sells 1 one-off in-app purchase and Main Idea sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Main Idea holds the better App Store score, 3.7 against 3.1. That said, the two scores are not equally well evidenced: MathTappers has 80 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of MathTappers's written reviews are positive against 42% of Main Idea's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

MathTappers ships an update every 33 months, Main Idea every 22 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
