One of the most common questions we are asked is how our library of digital content supports the Common Core.  The easy answer is that our entire library has been aligned to the Common Core standards, so teachers can find resources related to each standard.  The more complex answer is that there are many pieces of content that can be used in flexible ways to support each individual standard, and it is up to teachers to choose the content that best supports their lesson and their students.

Here are five pieces of digital content a teacher might choose from StarrMatica’s library to support and enhance the teaching of: CCSS.MATH.CONTENT.1.MD.A.2 Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. 

12How Tall

Students estimate and then measure how tall objects are with non-standard measuring tools.


13Estimate and Measure with Chef Pierre

Students estimate and measure the length of Chef Pierre’s pans using cinnamon rolls.


14How Big Are You?

Students estimate how many of a non-standard measuring tool it takes to measure a larger dinosaur. Then measure to check your estimate.


15Measuring Crystals

Students estimate and then measure crystals with non-standard measuring tools.


Read the following books with your students to explore non-standard measuring. In the first book, Several small worms use their varying lengths to measure the vegetables in a garden.  In the second book, three friends–Laura, Juan, and Sarah–compete in a sand castle building contest and measure their castles with spoons, shovels, and bare feet.
