Learning How to Measure with Puppies and Kittens [PDF ebook] 

Through cute animal pictures and simple language, this text will teach elementary math students about using nonstandard and standard measurements to measure length, width, and height. This book supports the Common Core Mathematical Standards Basic by helping students figure out the length of an object as a whole number of length units by counting how many multiple copies of a shorter object fit end to end along the original object as well as using rulers, yardsticks, and measuring tapes. Fact boxes and activities enhance the math concepts.
