Addictive logical math apps

English graded-reading software

Early reading and foundational math apps

Delta (Graded-Reading)

Reading is the most important skill. Designed for primary and middle school, Delta, a browser-based graded-reading app (Windows and Mac OS X), gives your child endless hours of reading practice. Your child can get 200 hours of reading practice per year during those years. She will read interesting materials (simplified classics, folktales from all over the world, simple non-fiction), carefully rewritten and graded according to difficulty level. There are built-in exercises throughout to check your child’s progress. To subscribe or enquire, write to teachbasix@gmail.com

Find The Sign

Addition. Subtraction. Multiplication. Division. Basic arithmetic with a twist. The rules are simple. You have to put +, - , x, or ÷ signs in the blank boxes so that the number sentences work. You need a bit of logic and a bit of calculation to solve each puzzle.

Magic Square

Math game blending addition subtraction with logic. Helps brain development. The rules are simple. Some numbers are already filled-in in a 3x3 square. You have to fill in the rest of the numbers so that the sum is the same across each row and each column.

Pair Pattern

An early introduction to algebraic thinking – these sums ask children to derive the relationship between pairs of numbers. The right hand side numbers are related to the left hand side numbers. Observe the three pairs of numbers carefully and find the relationship.

Magic Triangle

Number puzzle for primary level kids. Hones calculation and logical reasoning. The rules are simple for a child to understand. Some numbers are already filled-in. You have to fill in the rest of the numbers so that each number is equal to the sum of two numbers immediately below it.

Multiplication Kakuro

If you like Sudoku, Kenken or Addition Kakuro, then you will surely love Multiplication Kakuro! This is currently the only Multiplication Kakuro app in the play store. Makes multiplication-division practice fun. Great for classroom use. Sudoku type logic.

Place Value – number concept

Three activities – 'Tell Number', 'Make Number', and 'Big or Small' are aimed at strengthening your 3-6 year old child’s number concepts by familiarising them with the place-value based number system.

First Math – math for kids

Useful for teaching basic addition subtraction using virtual place value system. For 4-6 year olds.

Mental Math

Useful for teaching advanced addition subtraction (double digit, with or without carryover) using place value system. Can aid self-learning through help animations

Skip counting – number pattern

In this app, students can practice skip counting (repeated addition of a number to a given start number). This can be helpful for learning multiplication later on (after all, multiplication table of 4 is nothing but repeated addition of 4, starting with 4).

First reading

Read sentences using most frequently occurring phonetic and sight words. The app uses 500 most frequently occurring phonetic and sight words, and sentences constructed from those words. Aim is to make reading of the basic words fast and automatic.

Nonogram

Japanese puzzle that improves that your logical and spatial reasoning skills. Our Nonogram app is free and randomly generates an unlimited number of Nonograms, rather than most apps in the Play Store that have only pre-fed designs.
