Title: Monster Math
Author: Grace Maccarone
Illustrator: Marge Hartelius
Recommended Grade level: Pk-1
Common Core Standards
addressed:
Understand the relationship between numbers and quantities;
connect counting to cardinality.
Count to answer "how many?" questions about as many as
20 things arranged in a line, a rectangular array, or a circle, or as many as
10 things in a scattered configuration; given a number from 1-20, count out
that many objects.
Use addition and subtraction within 20 to solve word problems
involving situations of adding to, taking from, putting together, taking apart,
and comparing, with unknowns in all positions, e.g., by using objects,
drawings, and equations with a symbol for the unknown number to represent the
problem.1
10 can be thought of as a bundle of ten ones — called a
"ten."
Summary: This book is about 12
little monsters completing several activities throughout their day. Each time the monsters move to the next
activity, a monster disappears.
Rating**** This book is good to
use when introducing subtraction, one less method and counting backwards
(12-0). Monster Math is a fun rhyming
book for both beginning readers and beginning subtraction.
Classroom Idea:
This
book can be used to introduce subtraction, number sense and descending
numbers. I would introduce vocabulary
(minus, take-way), symbol (-) and discuss the difference between adding and
subtraction. I would use the following
materials:
-Visuals
(12 little cut-out monsters)
-Counters
-Pencil
& paper
-Number
line
-Cup
-Cup
As
I read the story I would have the student follow the story by placing a counter
in a cup every time a monster disappears.
Students would also participate by removing monsters from the white
board and pointing to the number of monsters remaining on the number line.
For
1st graders I would use higher order thinking- Students would write
number sentences (12-1=. 12-3=). We
would discuss and identify key vocabulary words for subtraction. Also, we would compare and contrast the
answer before to the answer now. Ex.
12-1=11 vs. 12-3=9
