Hey there everybody! Our first topic has come to an end and tomorrow we will quiz on what we have learned. Be sure you know the following vocabulary: bar graph, pictograph, average, digit, quotient, product, sum, and difference. Here are some resources that you can use to study. Remember, the Topic 1 Review is assigned as homework!
Work through the activities in the Blendspace for extra practice:
Division is splitting a larger amount into equal groups or finding out how many are in each group. In this topic, we identified factors, common factors, and found the greatest common factor of whole numbers. We explored rules of divisibility such as, "A number is divisible by four when the number formed by the last two digits of that number is divisible by four." For example, 1312 is divisible by four because the last two digits form the number 12 and that is divisible by 4 (1312 / 4 = 328); whereas 1319 is not because 19 is not divisible by 4 (1319 / 4 = 329.75).

We also learned some neat ways to divide by ten. We explored related division problems like 450 divided by 5 and 450 divided by 50 and found patterns to help us divide by multiples of 10. You can practice your multiples by playing Ghost Blasters. Then, we moved into calculating the mean and finding the range. Remember! Range is the difference between the largest and smallest number of a data set, and average is found by computing the sum of a set of numbers and dividing by the number of addends! Throughout, we used the long division algorithm to solve division problems. Check out all the stuff you can use on the web for practicing division under the Topic 3 Resources.
Becoming a good divider, if that is a title, takes practice! So, here is a Blendspace review that you can use to practice all the skills we have learned in Topic 3!
We just finished learning about 3-D shapes, angles, circles, and other polygons. Review the topic's concepts by checking out the Blendspace module below. Things to remember:
We have done a ton and learned a lot this topic! Here are a few links that you may want to explore:
