Description

The naïve bean president of the legumes nation has mistakenly thrown pies against the world leaders. Use additions and subtractions to defend from your opponents in bakery dispute and restore world peace. The game features six chapters in story mode to learn and reinforce subtractions and additions concepts. In story mode, the game teaches you to complete the operations by counting beans on the screen, in our so-called Bean Algorithm. If you're already familiar with the story mode, then you can jump right into practicing operations in the practice mode, and prepare your kids for an assessment. Collect all the medals by completing the key tasks in the game, and brag about it for being the best.

Instructions

Play through this interactive game to learn about Fluently Add And Subtract Using Standard Algorithm. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

Standard algorithms for addition and subtraction are based on decomposing numbers written in base-ten notation; this reduces addition or subtraction of two multi-digit whole numbers to a collection of single-digit computations of place-value units.

Position the unknown quantity on the left and right side of the equal sign.

While moving to the right across the places in a number the digits represent smaller units.

Place value in base ten groups numbers in bundles of 10’s with each place value being 10 of the prior unit. (10 ones = 1 ten, 10 tens = 1 hundred etc)

Use algorithms for addition and subtraction that allow for scholars to regroup place value when necessary.

For subtraction you can also check all potential ungroupings first and then perform all the subtractions.

For subtraction, students need to evaluate whether ungrouping and regrouping is necessary. Students may either treat each place value column separately and ungroup and subtract before moving on.

Discussion Questions

Before the Game

If you want to remove some things from a group, what mathematical operation would you use? If you want to make a group of objects larger, what mathematical operation would you use?

After the Game

What clues did you use to decide whether you needed to add or subtract to solve the equation? How can we check our answers to an addition problem? When was it necessary to carry numbers during an addition problem? When is it necessary to borrow from the next column of numbers in a subtraction problem?
