These are great for children who are having a hard time grasping the concepts.

• Chicken Exercise - We work through this problem in this exercise: Matt has two poultry sheds. He gives the hens a safe place to live and plenty of food. He currently has 7 hens in the first shed. He plans to move 5 of those hens to his second shed. How many hens will be left in the 1st shed when 5 hens leave?

### Practice Worksheets

I went in a lot of different directions with these to help teachers and students see different angles.

### Quick Tips for Solving Questions Like This:

The first tip is pretty obvious. Start by pay attention to the keywords in the language that you are provided with. If you see the following phrases or words: altogether, and, combine, increase, more than, plus, sum, or total; you can quickly understand that you will be adding two or more values together. Likewise, if you see the phrases or words: decrease, difference, fewer than, left with, less than, minus, or take away; you will need to subtract two or more values. Some problems may use words to indicate numbers. We would encourage you to write those words as numbers. To make the problems more real for you, we would encourage you to draw the problems into simple diagrams for yourself. It is much easier to see if something makes sense visually. You will not be able to do this with problems that involve very large numbers, but a general guided drawing can go a long way in those cases. The more practice you get with this, the easier it will be for you.

Greg Guacamole and Peter Pineapple went out and bought a few slices of pizza for dinner. Greg had 4 slices of pizza and Peter had 3 pieces of pizza. They put all their pizza into a pizza box. How many slices of pizza were in that box?

Solution: The "all their pizza" tells us they we are looking for a total. To this we just find the sum of all of the slices of pizza that we have. Greg has 4 slices and Peter has 3, so the total would be equal to their sum.

4 + 3 = 7
The answer would therefore be 7 slices of pizza in total.

### Example Subtraction Word Problem

Working off of the previous word problem (above). Later that same day, Peter Pineapple went in the refrigerator and grabbed that box of pizza and there were only 2 slices of pizza left in box. Greg Guacamole ate those slices. If there were originally 7 slices in the box, how many slices did Greg eat?

Solution: The box started with 7 slices and after Greg ate, there were only 2 slices left. This means that we need to find the difference between the number of slices remaining (2) and how many slices we started with (7). To put this in math terms:

7 - 2 = 5.
So, Greg must have eaten 5 slices in total. Man, that is a lot of pizza.
