This game is called Field of Fractions. It has students plow fields and plant crops to show how to create fractions and how to determine what fraction of a whole something is. This would be a great way to teach students basic fractions and how they can divide rectangles into fractional pieces. I would recommend using this with 2nd/3rd grade and up.
This activity is called Equivalent Fractions and can be used to help students discover which fractions are equal to one another. It uses something children can relate to (food) to relate fractions to one another. When you aren't close it tells you to keep trying and when you get equivalent fractions it gives you a giant smiley face and says "Great job!" I would recommend this for 3rd grade and up.
This is a matching activity called Identify Fractions. It's a great matching activity that would allow students to start understanding fractions. This is the stage where they say 3 out of 4 rather than three quarters or three fourths. The game can be reset so it is different each time. I would recommend this activity for kindergarten and above as long as they can read it (or have help) and can count up to ten. This could be used as an individual or whole class activity (on the Smart Board).
This activity is called Pizza and Fractions. This is another way for students to visualize fractions using something they can relate to - pizza. The students can estimate the fractions by looking at the picture, or they can click on division and see which fractions it is looking for. They can hit the reset button in the upper right corner to get a new fraction. They can also check their answers by checking the "left over?" and "eaten?" boxes. This activity would probably need to be accompanied by a worksheet where they would draw the pizza in a circle and write the fraction next to it. I would recommend this for 2nd/3rd grade and above,
This is a basic Fraction Multiplication activity. It shows students how to multiply fractions by having them create fractions and then laying them over one another to show that that double-shaded area is the new fraction created by the multiplication. This would be a great Smart Board activity to go through as a whole class. I would recommend this for 4th/5th grade and above.
This activity has students match the Name of Fractions with their mathematical fraction equivalent. This would be a great follow-up activity to the matching activity detailed above. This would work best for students in 1st/2nd grade and above. This would be a great beginning activity that would also work well on the Smart Board.
