A Fair Bear Share Author: Stuart J. Murphy Illustrator: John Speirs Publisher: HarperTrophy Copyright: 1998 ISBN: 0064467147 Number of Pages: 40 Ohio Standards Alignment: Grades 1–2
Mama Bear sends her cubs to gather the ingredients for a pie. She tells them that if they get enough, they will each get their fair bear share of the pie. As the cubs return from each gathering trip, Mama bear helps them count the contents of each basket and add to get the total. Drawings show collections of up to 100 objects grouped by tens to reinforce placevalue ideas for students in grades 12. In addition to the mathematical ideas, the story also shows what happens when one member of a group does not do his/her fair share.

Number, Number Sense and Operations StandardBenchmarks (K2) M. Add and subtract twodigit numbers with and without regrouping. A. Use place value concepts to represent whole numbers using numerals, words and physical models. Grade Level Indicators (1) 5. Use place value concepts to represent whole numbers using numerals, words, expanded notation and physical models with ones and tens. For example:
a. Develop a system to group and count by twos, fives and tens.
b. Identify patterns and groupings in a 100's chart and relate to place value concepts.
c. Recognize the first digit of a twodigit number as the most important to indicate size of a number and the nearness to 10 or 100. Grade Level Indicators (2) 1. Use place value concepts to represent, compare and order whole numbers using physical models, numerals and words, with ones, tens and hundreds. For example:
a. Recognize 10 can mean "10 ones" or a single entity (1 ten) through physical models and trading games.
b. Read and write 3digit numerals (e.g., 243 as two hundred forty three, 24 tens and 3 ones, or 2 hundreds and 43 ones, etc.) and construct models to represent each.
