Variable A letter or symbol in an equation or expression that may take on different values
Pronumeral A letter used in place of a number Another name for variable
To solve an equation By doing the same to both sides Must always keep the equation balanced "What ever you do to the LHS you must do to the RHS"
To make the equation true... The LHS= must =RHS
If you have unknowns 'pronumerals' on both sides of the equation You need to get all pronumerals onto the one side. Usually moving the smaller coefficient
Coefficient The number in font of the pronumeral.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
