Algorithms for Algorithms

When students create a computer program they are creating an algorithm or listing the steps needed for something to happen.  Students also use algorithms in mathematics; in this case the algorithms would be the steps taken to divide fractions or multiply decimals.  Students were challenged to create a program in Scratch that reteaches a math concept. By elaborating on their understanding of the math by teaching the concept to others, this will help them store this skill in their long term memory!

Multiplication the Fun Way

Students in 4th Grade read stories from the book Times Tables the Fun Way that provides tales and visuals to help students remember their multiplication facts.  For example, for 6 x 6 their are the two 6s that are wandering through the desert an and they are “thirsty sixes”.  Thirsty six sounds like 36, so students will remember more easily that 6 x6 = 36.  They recreated these stories by creating a program in Scratch, a free programming software from MIT.  Here are links to their work:
