NEVER use "skill and drill" worksheets. These are the worksheets just made up of columns of problems. There are better materials out there, so do not resort to skill and drill. The very worst problem of skill and drill worksheets is the greatly increased chance of a practiced mistake. The same problem will likely appear several times on the same sheet. A wrong answer once means a wrong answer several times; and a practiced mistake takes hundreds of correct repetitions to fix. This danger alone is important enough to never use any worksheet. I am quite serious about how difficult it is to repair a practiced mistake. Learning is hard enough. Re-learning is much more difficult.
During classroom time, you can even make division activities more interactive. Create groups of students in the classroom and give them all some objects like marbles, or other small objects. You can tell your students how many they have, and how they should divide out the marbles with their friends. This will quickly help them understand the basics of division, and added onto an understanding of adding, subtracting and multiplying they will soon be on their way to understanding more complex parts of their mathematics curriculum. Keep your students interested, and if you are helping your children, remember to keep encouraging them. No matter how hard they find it, they will soon get the hang of it.
Here are some other sharing subjects to explore: Take Away Store - hot chips (35 per cup), milk shakes (3/4 cup of milk per shake) - how much for 26 people? Concert -toilet paper - 10 sheets per person, 100 sheets per roll, 3 000 people attending- how many rolls? Dog Shelter - 1 cup of biscuits large dog, 3/4 cup for medium dog etc - how much for 10 big, 5 medium etc? Jelly bean competition - Big jar took 12 bags of jelly beans - 124 beans in 1 bag - how many beans in total? These are a great way to explore a range of math skills. Choose one subject and choose questions that relate to that. An obvious one is school: At Collins State School there are 23 students in Kindergarten, 24 in Grade 1, 23 in Grade 2, 18 in Grade 3, 22 in Grade 4, 17 in Grade 5, 19 in Grade 6 and 22 in Grade 7. How many students are there in the whole school?
