1. What is a good definition of percent? You should use words symbols, pictures and numerical examples in your definition.

2. How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show your answer. 1/5=20% 1/5x3=60% 10=60 3:2 =part/part+whole= fraction 1/5=20% 1/5x3=60%

3. Show 3 different ways to find 35% of 80. 1.find out what 1% is... 80 divided by 100 =8 8=1% 1%/8x35 =28. 35% of 80=282. 5 goes into 35 7 times 5% is 4 4x7=483. 1% is .8. .8 x 10=8 .8 x 10=8 .8 x 10=8 8+8+8=24if 10% is 8, then 5% is 4. so 24 + 4=28

5. .The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms. Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not. 20/40=50% 11/20=55% Ms. Stanzi is Correct because there are more kids in Ms. Lowrey's class.
