Counting Coins

Alright 2nd graders, today we are going to be doing a collaborative assignment, where you will get to work with your table groups on Jamboard! As you know, we’ve been reviewing how to count coins, as it is really useful for when you need to buy something, or when you’re getting change back after a purchase. Remember from yesterday, pennies are worth 1 cent, nickels are worth 5 cents, dimes are worth 10 cents, and quarters are worth 25 cents. If you don’t remember which coin is which, be sure to ask your table group or myself. Now, let’s have everyone open up the Jamboard link that corresponds to your table number!

Slide 1

For this first slide, count up each of the four groups of coins, and write down that number in a new sticky note below each group, or just edit the existing sticky note under each group. Do this work individually, but if you get stuck, ask your table partners for help first.

Slide 2

For the second slide, you may now work with your group to figure out how many coins you can put into each of the four sections, to match the given price tag. Remember, there are many correct answers for each price tag! Feel free to duplicate the coins, but only if you have run out of coins to use.

Slide 3

This final slide is similar to the last slide you did, except this time, you will be finding three different ways to represent 39¢.

Teacher instructions: Make sure to have a backup copy! If something happens to one of the Jamboards that the students are editing, you can simply copy the original again and send them the link to it. If you notice that a student tends to only use the same 2 or 3 types of coins, encourage them to use all 4.

Goals: This second grade math lesson is intended for students who have already had practice identifying coins, and who have at least some experience using them to match certain prices. The Jamboard is a useful tool in this lesson as it allows the students to use an interactive, visual representation of the math concepts they’re using, in a collaborative environment where they can get feedback from their peers. Each of the three slides challenges them to think about this topic in different formats, without straying from the intended purpose of the lesson.

  1. Jack, this is an impressive lesson. Well designed and clearly explained to students. Good instructions to fellow teachers, as well. I like that you have 3 different tasks to support the instructional goal. That gives students multiple ways to demonstrate their learning.

    You are wise to advise teachers to make a back up copy. Lots of elements in here that could get lost. Although you might consider having one image of each denomination and let students “duplicate” as many of each as they needed.
