Share Article

PJ Apps, the innovator of math games that skillfully blend patterns with math instruction, is today releasing their latest learning game for the iPad, Crackers and Goo. Crackers and Goo uses patterns integrated with math strategies to teach children critical thinking skills, showing them how to look at a problem from multiple perspectives and come up with creative solutions.

No other math app offers such a powerful educational experience in one package. - Theresa Gorey, Learning Specialist

“I can’t tell you how often when I ask a child what '99 + 99 =', they ask for paper and pencil, instead of quickly recognizing the better strategy of adding two 100’s and subtracting 2,” said Peter Glynn, elementary math specialist and co-creator of Crackers and Goo. “We need children to grow into adults that can critically analyze a problem and identify an efficient strategy for solving the problem.”

Children will find Crackers and Goo a fun and challenging application because it uses pattern puzzles to highlight mental math strategies. Parents and teachers alike will appreciate the math hints and equations that are built into the game to provide children with the learning support they need to improve their number sense. Crackers and Goo was specifically designed for the Common Core Standards of Mathematics.

Crackers and Goo has over 6,000 games in 16 different levels of math called skill steps, with many games of increasing complexity at each step. This provides children with enough variety and repetition for deep understanding and long-term retention of the math skills they learn.

Children from ages 4 and will learn and practice the following skills with Crackers and Goo:

  •     Counting and skip-counting by 1's, 2's, 5's, 10's, and 100's
  •     Pattern recognition and sorting

  •     16 different steps of play, each with over 5 hours of play and focusing on increasingly complex math skills
  •     Demo mode showing how to play the game
