In the classroom, use Electric Sums – Lumio Addition & Subtraction (Full Version) as an instructional support tool. Kids should have knowledge of place values through hundreds and should be able to add and subtract two-digit numbers before playing. They should also know how to write numbers in expanded forms. To start, kids should work individually to complete a level within the Fix It Digit! mode. Then, come together as a class and discuss the level: Were they able to earn three lightning bolts? Continue to allow kids to complete levels and move to the next game mode when they are ready. As an extension activity, have kids write their own addition and subtraction problems and switch with a partner to solve them.Continue reading Show less
Electric Sums – Lumio Addition & Subtraction (Full Version) is organized into two learning pathways: Fix It Digit! and Digit's Black Out. Each mode includes more than 30 levels that begin by helping kids build comprehension and end by reinforcing concepts and helping build fact fluency. In Fix It Digits!, kids complete electric circuit puzzles to help Digit fix items around the house. The puzzles require kids to decompose numbers and then add them using place value. In earlier problems, kids decompose addends and the sum is calculated for them. Later problems require them to calculate sums on their own. In Digit's Black Out, kids help Bobo the robot join points on a number line. The learning pathway is similar to Fix It Digit!, but a number line is introduced, kids work with subtraction problems, and numbers are partially decomposed, or partitioned. Kids can earn up to three lightning bolt rewards for each correct answer.
Electric Sums – Lumio Addition & Subtraction (Full Version) is a game that teaches kids strategies for addition and subtraction with 3-digit numbers, addressing an important Grade 3 Common Core math standard. Kids decompose numbers and add or subtract using place values. They begin by using a slider to break numbers into hundreds, tens, and ones. This helps kids add larger numbers by adding the digits in each place value. As they progress through the game, kids use a number line to help them add and subtract. This strategy helps kids visualize solutions as they work toward the use of equations and the concept of balancing equations in order to solve problems. If kids struggle, they can access visual cues and hints. Constructive feedback is given for incorrect solutions.
