Electric Sums - Lumio Addition & Subtraction (Full Version)
'The learning support is superb and the app feels more like a sophisticated game rather than an instructional app.' The iMums, 5 stars
Solve addition and subtraction puzzles and uncover a story about gadget fanatic Digit and his robot Bobo. Problems and story episodes unlock as learners progress through 2 structured learning pathways.
1) Fix It, Digit!
Digit must complete the electric circuit puzzles to fix the gadgets and he needs your help! These puzzles are based on the full partitioning strategy used in school. Large numbers are broken into place values (469 = 400 + 60 + 9) and then added together.
2) Digit’s Black Out!
The ship is dark, the lights went out. It's time to give Digit a shout! Digit’s robot, Bobo, gets to work joining two points on an electric number line. Kids add and subtract big numbers with small steps! These puzzles are based on a partial-partitioning number strategy. Working with a number line model enables little mathematicians to visualize the computation as they work closer and closer to the sum or the difference.
3 animated tutorials walk learners through two different methods of adding and subtracting.

The learning objective of the app is for children to understand and practice general methods for adding and subtracting 3-digit numbers using place value. These electric puzzles are designed to help kids maintain and build their fluency with adding and subtracting within 1000.
Number sense and computational skills are built on a firm understanding of place value. In Electric Sums, kids demonstrate a deep understanding of place value beyond algorithms.
