This Thanksgiving Inspired DIY lesson on Subtraction uses materials you probably have at home. (Please note that this lesson should be presented to a child who already understands the concept of numerals at least till ten and the concept of addition; see the links below.)
There are different ways you can explain the mathematical operation of "subtraction" to a child - the process of taking away/removing objects from a collection: a 🦃 hen/turkey ate the kernels (thus the difference is less by what the turkey ate) or a child can use fine and gross motor control to punch out holes/kernels we are subtracting or to cut the subtrahend kernels.
The 1st number (from which we are subtracting from) is called a minuend, while the number being subtracted (2nd number) is called the subtrahend. The result is called the difference.
Subtracting/taking away can also be presented by cutting, thus resulting with less of something.
Once the equation is solved, a child would choose the correct difference/result of the subtraction from number stickers.
