Math Potatoes: MindStretching Brain Food Author: Gregory Tang Illustrator: Harry Briggs Publisher: Scholastic Press Copyright: 2005 ISBN: 0439443903 Number of Pages: 40 Ohio Standards Alignment: Grades 1–4
Another in a series of mathematically related rhyming books by Greg Tang, these counting riddles involve food and other visual items engagingly illustrated by Harry Briggs. The items to be counted are laid out in patterns that allow the reader to form numerical groupings that make counting larger numbers of objects easier for many students. Solutions are given in the back of the book, but students may come up with other ways to group and count the objects, leading to some lively discussions.

How to Use This Book

 These poems and accompanying illustrations can be used individually, in groups, in a series, or all together to help children look at and think about strategies for counting a large number of objects.
 The symmetry and the clever riddles embedded in the poems can also help children visualize number groupings and the resulting shortcuts.
 Children should be encouraged to create their own patterns and groupings of objects.
 A literacy connection can be encouraged by having children create poems about their groupings.
 Children can present their riddles to each other or to the class to show a variety of strategies that make sense to individual students.
 A class book, similar to Math Potatoes, could be compiled from problems and drawings created by the children.


Highlights and Insights

 This book provides an excellent context for discourse and developing reasoning and number sense skills.
 Students may need time to become familiar with the format of the book when reading a Greg Tang book for the first time.
 Having the mathematical information displayed and presented in multiple ways helps learners who may not get the information in more conventional ways become more mathematically proficient and show what they know and are capable of understanding.

Number, Number Sense and Operations StandardBenchmarks (K2) F. Count, using numerals and ordinal numbers. I. Model, represent and explain multiplication as repeated addition, rectangular arrays and skip counting. Benchmarks (34) G. Model and use commutative and associative properties for addition and multiplication. Grade Level Indicators (1) 2. Recognize and generate equivalent forms for the same number using physical models, words and number expressions; e.g., concept of ten is described by "10 blocks", full tens frame, numeral 10, 5 + 5, 15  5, one less than 11, my brother's age. 4. Count forward to 100, count backwards from 100, and count forward or backward starting at any number between 1 and 100. Grade Level Indicators (2) 7. Model, represent and explain multiplication as repeated addition, rectangular arrays and skip counting. Grade Level Indicators (3) 8. Model, represent and explain multiplication; e.g., repeated addition, skip counting, rectangular arrays and area model. For example:
