This powerpoint presentation includes 72 slides with double ten frames. Students can use their knowledge of 5 and 10 to figure out how many reds are on the top frame and how many blues are on the bottom frame. They also figure out the difference between reds and blues and/or the combined total of the two colors. Teachers also can ask how many more reds are needed to fill the top frame? How many more blues are needed to fill the bottom frame? This is a great whole class activity, small group activity, or center idea.
