Regrouping fractions can be tricky. What is 5 3/10 - 3 4/5?
The answer is 1 1/2. Here is a short, super-silly video that I shared with my students demonstrating "The Trick" to master regrouping fractions: https://www.youtube.com/watch?v=Ts9hFs1ERxc&index=11&list=UUuRe2FrYBi7PZOFCoDhfaDA
The Sugar Act of 1764 actually lowered British customs duties on sugar and molasses. Why did it cause unrest among merchants in America?
The Sugar Act meant to raise revenue. The earlier Molasses Act of 1733, which had imposed a tax of six pence per gallon of molasses, had never been effectively collected due to colonial resistance and evasion. The revised Sugar Act did indeed lower the tax from six pence to three pence. Merchants like John Hancock were angered by this because it made their illegal, smuggled goods less appealing to colonist trying to avoid the tax. Hancock was angered by the Sugar Act and Townshend revenue acts – not on political grounds but because they threatened the profitability of his business.
How can a teacher group students to achieve the the best results? Some educators firmly believe that a teacher should arrange the groups so that students of all levels are represented in each team. This is called heterogeneous grouping of students. Others believe that a teacher must organize the students by ability levels- a homogeneous grouping of students. Research shows that there are advantages to both methods, depending on what the teacher wants to accomplish. Describe the benefits of both grouping styles.
Both grouping styles (heterogenous and homogeneous) are appropriate in a elementary classroom at different times, for different reasons. If the purpose of the group learning activity is to help struggling students, heterogeneous groups may achieve optimal results. Children enjoy learning from each other and sometimes a peer can explain something in a different, more effective way than a teacher can communicate. On the other hand, if the purpose of the grouping is to encourage medium ability groups to learn at high levels, homogeneous grouping would be better as long as every member of the group is an active participant.
