Problem: Article: Empty your change jars, pants pockets, coin purse, piggy bank, and any other places you have holding your coins. If you want to be really thorough, check between the couch cushions and in your dresser drawers as well. Create individual piles for each coin type. All coins worth a certain amount should be grouped together. Give yourself plenty of room so you can keep the groups separated from each other. For instance, if you are using US coins, you should have a pile of quarters, a pile of dimes, a pile of nickels, and a pile of pennies, as well as piles for half-dollar and dollar coins if you have any. Pull one pile of a particular coin type in front of you. Put the rest of your change aside for now. You'll get to those coin types later. For example, if you're working with euros, you should have 8 separate piles of coins -- 1 pile for each coin type. Set 7 of those piles aside and place the other pile in front of you. Count one coin type at a time. Start creating short vertical piles, with each stack having 10 coins in it. After stacking all of them, you may not have enough to make a final stack of 10; that's fine. Set the extras aside.  Stacks of 10 work best if you have a lot of coins. 10 is an easy number to count and multiply, so it makes a large amount of coins manageable. If you aren't working with a lot of coins, try making stacks of 5 instead. If you're working with very few coins (less than 10), just make 1 stack and count the exact number of coins in that stack. Write that number down. Look at your stacks of that coin type and count how many full stacks you have. Once you have that number, multiply it by 10. That is how many of those coins you have in total.  For example, say you have 8 stacks of one coin type. Multiply 8 x 10 = 80. You have 80 of those coins total. The number you get is the total amount of money you have in that coin type. Once you have the final amount, write it down on a piece of paper.  Multiply 80 coins x coin worth = total amount of money you have in that kind of coin. For example, if you are working with US dimes: 80 dimes x .10 cents = $8.00. If you have a few coins that did not fit into a stack of 10 for that coin type, don't forget to factor the worth of those coins into your final amount.  For example, if you have 8 stacks of dimes: 80 dimes x .10 cents per dime = $8.00. If you have 3 extra dimes, add that amount: $8.00 + .30 cents = $8.30. This is the total amount of money you have in dimes. Make stacks of 10, count the stacks, then multiply by 10. Take that number and multiply it by how much that kind of coin is worth. Write down the final amount for each of the different coin types.  For example, if you have 3 stacks of quarters: 3 stacks x 10 coins per stack = 30 quarters total. 30 quarters x .25 cents per quarter = $7.50. If you have 2 extra quarters, add that amount: $7.50 + .50 cents = $8.00. This is the total amount of money you have in quarters. Plug each coin type's final amount into a calculator. Hit the equal sign on the calculator for a final tally. That number is the total amount of money you have in change.  For example, you have $1.53 in pennies, $2.10 in nickels, $8.30 in dimes, and $8.00 in quarters. Add those figures together: 1.53 + 2.10 + 8.30 + 8.00 = 19.93. The total amount of money you have in loose change is $19.93. To avoid counting huge piles of coins, get coin wrappers from your local bank and roll the change yourself. Roll each coin type separately by denomination. Banks require a specific number of coins per roll, depending on the coin type. Roll the coins separately according to your bank's requirements. If you aren't sure what the requirements are, ask a bank teller when you pick up the wrappers.  For example, if you're working with US coins: 50 pennies per roll, 40 nickels per roll, 50 dimes per roll, 40 quarters per roll.  Deposit the rolled change into your bank account or ask the bank teller to give you larger bills in exchange for the rolled coins. If your bank doesn't give out coin wrappers, you can order them online.
Summary: Gather all of your coins together. Separate the coins into piles based on their type. Work with one coin type at a time. Create stacks of 10 coins each. Count the number of stacks you have and multiply by 10. Multiply the total number of coins you have by the coin's value. Factor in the leftover coins that didn't make a full stack of 10. Repeat this process for the other coin types you have. Add up the final amounts for each coin to get a total amount. Roll your change as you get it.

Summary:
Write your notes on a piece of paper. Put your notes in your hoodie pocket. Sit behind someone so that your are obscured from the teacher's view. Try not to take too long; teachers likely notice who finishes last and especially if the student does surprisingly well given that it took them so long to complete it (for the excuse "I was being careful and taking my time" can only work so many times).
