Smart Kidz Club Grade 4 Math App is curriculum-aligned for 9-10-year-olds to practice and master all the required grade 3 math skills. This app follows the US Common Core State Standards and consists of comprehensive math skills essential for GRADE 4 school students. Resources consist of activity books with math problems. Each Math Activity that requires complex solving, consists of a SCRATCH PAD option where the child can freely write on the screen (overlay) to solve the problems in writing if they so desire. Math activities cover all the required grade 4 skills such as coordinate plane, measurement, equivalent fractions, multiplication of fractions, ordering fractions, geometry, mixed operations, logical reasoning, variable equations, decimal numbers, adding and subtracting decimal numbers, time, patterns and sequences, data and graphs, probability, statistics, and variable expressions. Math Activities consist of 2 modes, practice and test. Each of these modes comes with a choice of the number of questions/problems that the child wishes to solve— 1) Practice Mode: The Practice Mode allows the child to solve each problem before advancing to the next problem while prompting them to try again if they choose the wrong answer. The Practice Mode is not scored. At the end of the practice mode, the child can try again with a new set of problems. 2) Test Mode. The Test Mode is scored and does not prompt the child during their attempt to solve the problem. At the end of the Test Mode, the child can try again with a set of new math problems or review their answers with detailed feedback and explanation. This app supports maths learning in homes by helping kids in grade 4 with their mathematical understanding and mastering math skills without any harmful distractions or ads.

ReceptionRating · Positive reviews · Number of ratings

Calculoo holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Math Master has 321 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Calculoo's written reviews are positive against 45% of Math Master's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Calculoo ships an update every 17 months, Math Master every 5 weeks. The most recent releases landed on September 9, 2026 and October 1, 2026 respectively.
