Math, Measurement, and Photography
A lesson for Kindergarten
By: Jessica McCord
Ms. McCord decided to go to store to buy items for the
classroom. She started with alphabet cards. Each card is
3 paperclips long. If one card is taken away, how many
paperclips will be left?
Hint for Problem #1
There are 6 paperclips altogether. 3 of them will go leave
when one card is taken away.
*BONUS* What sight word does this spell?
Ms. McCord also bought a pack of colored pencils. One
colored pencil is 6 paperclips long. How many times will 2
paperclips go into 6 paperclips?
Hint for Problem #2
Count by 2’s until you get to the number 6. How many
times did you count by 2’s until you got to 6?
Ms. McCord could not bring herself to leave the store
without buying some books. If 1 book is 5 paperclips
long, how many paperclips would we use to measure 2
Hint for Problem #3
Both books are the same size. If 1 book is 5 paperclips
long, then the other book must also be 5 paperclips long.
Ms. McCord decided that two books just weren’t enough.
She decided to buy one more book at the store. This
book is 10 paperclips long. How many groups of 5 can
you take out of the 10 paperclips?
Hint for Problem #4
Subtract 5 paperclips from the 10 paperclips until you get
to 0. How many times did you have to do that?
Problem #1: 3 paperclips left
Problem #2: 3 times
Problem #3: 10 paperclips
Problem #4: 2 times
MKM1. Students will group objects according to common
properties such as longer/shorter, more/less, taller/shorter, and
a. Compare and order objects on the basis of length.
MKP2. Students will reason and evaluate mathematical
a. Recognize reasoning and proof as fundamental
aspects of mathematics.
MKN2. Students will use representations to model addition and
a. Use counting strategies to find out how many items
are in two sets when they are
combined, separated, or compared.
