Math Mammoth: Understanding Statistical Variability and Distributions

Scholars investigate the spread of associated data sets by comparing the data sets to determine which has a greater variability. Individuals then interpret the mean as the typical value based upon the variability.

Is this a statistical question? The opening lesson in a series of 22 introduces the concept of statistical questions. Class members discuss different questions and determine whether they are statistical or not, then they sort the data...

What city has the most consistent temperatures? Pupils use the mean and mean absolute deviation to describe various data sets including the average temperature in several cities. The 10th lesson in the 22-part series asks learners to...

Here is a nice activity about recognizing the difference between a statistical question and answer and one that anticipates a fixed answer. From this, your future statisticians will develop an understanding of variability and be able to...

Box in the similarities and differences. The 19th lesson in a unit of 22 presents class members with multiple box plots to compare. Learners use their understanding of five-number summaries and box plots to find similarities and...

Make multiplication of decimals easier by applying the distributive property. Pupils investigate how they can use the distributive property to multiply decimals. After learning the strategy, they work on some practice problems at...

Review general math skills before that quiz!  25 questions in five categories - number sense, computation, geometry and measurement, algebraic thinking, statistics and probability.  Tip: have each student use a white board to...

Scholars apply their knowledge of statistical questions to determine which questions meet the criteria. Grade 6 Claim 1 Item Slide Shows offers a couple of practice problems for scholars to discuss.

Who needs parentheses, anyway? Understanding how to apply the distributive property—and how to get rid of parentheses—helps scholars conceptually understand why it is necessary. Guided practice problems help build confidence to create...

This video is great preparation for order of operations and linear equations. There are two videos on the distributive property of multiplication. The first one showed why distribution works. This one shows the process in a clear and...
