Matching Pairs: Wave Characteristics - Directions

Using the Matching Pairs: Wave Characteristics Concept Builder is quite simple. There are five different Matching Pairs activities. Each activity requires the same task to complete - match eight different phrases or words into four different corresponding pairs. The eight numerical items display on a 3x3 grid. One of the squares on he grid is left open for purposes of displaying directions. The other 8 sqaures on the grid must be matched into four pairs. A match is made by selecting two of the squares and then tapping on the Check Match button. A square is selected by simply tapping on it; the square is outlined in red once it is selected. If you change your mind, tap it a second time to deselect it. Whenever two squares are selected, the Check Match button is displayed in the right-side column of the Concept Builder. When you are satisfied with your two selections, tap on the Check Match button. Your answers will be evalutated. If correct, the two squares are color-coded with the same color and can no longer be selected for the remainder of the Matching Pairs game. If your match is incorrect, you will unfortunately have to start the game over. But don't fear, it will be the same eight numerical items being displayed at a different location on the grid. Once you have made four successful matches, you will be rewarded the Trophy for that difficulty level.
