INTRODUCTION
diagrams, graphs, pictures, and tables—and answer questions about them. As they work on the
problems, children learn and practice the following problem-solving strategies:
- making lists or cases of possible solutions and testing those solutions
- identifying, describing, and generalizing patterns
- working backward
- reasoning logically
- reasoning proportionally
The development of problem-solving strategies and algebraic concepts is linked to the
development of number concepts and skills. As children solve the problems in this book,
they’ll practice counting, computing, applying concepts of place value and number theory, and
reasoning about the magnitudes of numbers.
Throughout this book, we emphasize the language of mathematics. This language includes
terminology (e.g., odd number, variable) as well as symbols (e.g., >, <). Children will see the
language in the problems and illustrations and use the language in their discussions and
written descriptions of their solution processes.
How to Use This Book
Inside this book you’ll find six problem sets—each composed of nine problems featuring the
same type of data display (e.g., diagrams, scales, and arrays of numbers)—that focus on one or
more problem-solving strategies and algebraic concepts.
Each set opens with an overview of the type of
problems/tasks in the set, the algebra and problem-
solving focus, the number concepts or skills needed to
solve the problems, the math language that is
emphasized in the problems, and guiding questions to be
used with the first two problems of the set to help
children grasp the key concepts and strategies.
The first two problems in each set are designed to be
discussed and solved in a whole-class setting. The first,
“Solve the Problem,” introduces children to the type of
display and problem they will encounter in the rest of
the set. We suggest that you have children work on this
first problem individually or in pairs before you engage
in any formal instruction. Encourage children to wrestle

FISHY PRICES
Name _____________________________________________ Date __________________
How much does each fish cost?
Match each price tag with its fish.
I’ll start with
Flash. His price tag
has the least
number.
1.How much does Flash cost? __
2.How much does Bronco cost? __
3.How much does Arty cost? __
4.How much less does Flash cost than Arty? __
I cost $2 more
than Flash.
I cost $1 less
than Bronco.
I cost the least.
