Smart Kidz Club Pre-K and KG Math App is curriculum-aligned for children up to 5 years old to practice and master all the required Pre-K and Kindergarten math skills. This app follows the US Common Core State Standards and consists of comprehensive math skills essential for pre-kindergarten and kindergarten students. Resources consist of both activity books and flash cards. 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 Flash Cards cover counting from 1-20. The Flash Cards are highly interactive and have a sequential mode useful for learning and memorization and a random/shuffled mode for practice and memory recall. Math activities cover all the required skills for pre-K and Kindergarten such as counting, comparing, identifying and classifying shapes, size, positions, measurement, addition, subtraction, sum and difference, graphs, time, patterns, introduction to fractions, and probability. 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 pre-K or Kindergarten with an introduction to early math concepts and practicing of mathematical skills without any harmful distractions or ads.
