In this post you'll find "2 truths and a lie" math activities, each with
error analysis questions built right in. Every activity is set up the same
way-- find the error (the "lie") on each card, then correct the error on the
student answer sheet. Students get practice identifying math errors in the
context of different math topics, and then with fixing those errors.

Here is the first card from an
integer operations "2 truths and a lie"
error analysis activity. There are 3 integer operations problems on the
card, along with 3 statements comparing the answers. Students solve the 3
problems then figure out which statement is the "lie". Students then fix the
lie on their answer sheet.

For this
slope "2 truths and a lie", students are presented with a graph, a table and a pair of coordinates,
as well as 3 statements about each representation's slope. Students need
to figure out which of the 3 statements is the lie, then correct that lie
on their answer sheet.

Students identify incorrect statements about zeros, vertex, axis of
symmetry, and/or y-intercept in this
key features of quadratic graphs "2 truths and a lie". All functions in the activity are factorable.

Are you getting ready to teach the laws of exponents and are looking for a few fun exponent rules activities? In this post I want to share the way I have taught patterns of exponents to arrive at 1, 0, negative and fraction exponents, as well as a few printable and digital exponent rules activities.

From there, we can continue dividing to find 3 to the zero power.

Students tend to believe that negative exponents will create negatives, so continuing the pattern to 3 to the -1 power helps them arrive at 1/3.

Fractional exponents, or rational exponents, are tricky to conceptualize. I wrote a blog post here on fraction exponents.

If you are teaching exponent rules soon, here are a few fun activities:

This new exponent rules "2 truths and a lie" error analysis activity tests students' understanding of exponent rules. Students identify incorrect statements when presented with expressions with exponents and their simplified forms. Students are then asked to fix each error on their answer sheets.

Next is an
exponent rules digital math escape room activity. Students must unlock 5 locks through simplifying 20 expressions with the
product rule, the quotient rule, the power rule, the power of a fraction
rule, the zero exponent rule and the negative exponent rule. Questions are
grouped 4 per puzzle, resulting in five 4-letter codes that will unlock all
5 locks.

"This is a great activity for students to practice their knowledge of exponents. It is self checking and able to be done independently or in groups. Students were very engaged."— Elizabeth E.

For a similar activity to the one above, just with evaluating, this exponent rules digital math escape room {with evaluating} asks students for their knowledge of exponent rules and then with evaluating their expressions.

"This activity was engaging and helpful for students to gain understanding with properties of exponents".— Chelsie S.

For a fun activity that doubles as classroom décor, this exponent rules math pennant activity asks students to simply expressions using the laws of exponents. Students can color their final pennants to make a colorful classroom display.

"My students loved this resource as a way to display their understanding! It was also a beautiful way to display student work within the classroom! Win win!"— Haley G.

Everywhere we look, there is data to interpret. There is data about sports,
elections, health and trends in our society. Learning how to read and
organize this data is important and empowering to students as they make
their way through their education.

Before becoming a teacher, I worked in the environmental consulting field between leaky gas stations and the Department of Environmental Protection. Part of my job was to collect data from soil and water samples at gas stations, interpret this data and report on it. I learned at this job that data interpretation is more subjective than I had thought. For example, dropping one more monitoring well into the groundwater upstream from a leaking tank will drop the overall average of the amount of gasoline in the groundwater at a leaky gas station. I lasted 3 years in that field before making the move to teaching. It wasn't for me.

And then there's the difference between mean and median when it comes to home prices and pay. Often the median is given in these situations so that outliers don't throw off the data making the numbers appear greater than they are. Interpreting this data and talking about the differences makes for interesting classroom discussion.

In this post I want to share a few fun activities you can use in your classroom to teach data analysis.

The first is a
mean, median, mode and range digital math escape room activity. Students must unlock 5 locks by finding mean, median, mode and range in 5
sets of data. Questions are grouped 4 per puzzle, resulting in five 4-letter
codes that will unlock all 5 locks.

This one also comes in a black and white printable version in the same file
if you'd like your students to work on paper.

Next is a
box and whiskers vocabulary sort where students sort 18 vocabulary terms onto the box plot for median,
outlier, upper extreme, lower extreme, quartiles and interquartile range
(I.Q.R.), then identify mean, mode and range given the box plot's
data.

Many professions require some level of data literacy. Whether in STEM
fields, business, healthcare, social sciences, and even in the arts, the
ability to work with data is an increasingly valuable skill for students to
learn.

Data presented as real-world problems encourages students to apply their
problem solving skills and build insights into the data. This
two way tables digital math escape room activity
gives students practice analyzing and evaluating the data presented in two
way tables. Students find missing table values, answer "and" and "or"
questions and calculate percentages represented by the data in this
activity. A printable version is also included.

Next is a
mean, median, mode and range math pennant activity
that doubles as classroom décor when students finish the activity. Students
find mean, median, mode and range given either 5, 6, 7, 8, 9, or 10 single
and double-digit numbers of data. Some answers require rounding.

Students follow a stock for a week, calculate the daily and weekly percent
change in price, estimate a line of fit for their scatter plot, find the
slope and equation of their line of fit and write a final analysis of their
data in this
stock market project. Above is my student Sam's final project and written analysis of the data
he collected. We did this project in our algebra class to cover percent
change. It's also a nice project for a
consumer math class.

In this
probability digital math escape room activity, student figure out the simple or compound probability in 20 scenarios.
Students find the probability of either one or two events in each question.
Questions are grouped 4 per puzzle, resulting in five 4-letter codes that
will unlock all 5 locks.

If you're looking for probability activities, I just recently made a
"2 truths and a lie" error analysis activity for probability. Students have to figure out which of the 3 statements is wrong (the
"lie") and correct the lie on their answer sheet.

Students analyze different depictions of data to find mean, median, mode,
range, totals and percentages in this
data math pennant activity. Data is presented in tables, line plots, line graphs, bar graphs,
histograms, box and whiskers plots, pie chars and sets of numbers. Students
can hang their finished pennants to show what they know as part of your
classroom décor.

And lastly, this
line plots digital math escape room
comes in both self-checking digital in Google Forms and in black and white
printable PDF. It asks students to analyze and answer questions about the
data shown in each line plot.

Knowing how to calculate the percentage of a number is pretty much the basis of consumer math. This skill comes up when calculating interest, tips at restaurants, discounts from coupons, tax on purchased items and with budgeting. It's such a simple but important skill for students to learn and really become comfortable with before graduation.

In this post, I want to share a finding percentage of a number handout for your students.

After sharing the sheet in the Facebook group, I got feedback to add 1% to the sheet. So when you download it, how to find 1% will also be there.

Today is Pi Day so I wanted to share a couple digital activity ideas. Both also come in print, if you prefer having your students work on paper.

The first is a Pi Day digital math escape room for middle school where students find either the area or the circumference of a circle, given diameter or radius. Students calculate their answers then type the correct 4-letter code to move to the next puzzle.

The next is a Pi Day digital math escape room for older kids. In some of the problems, students are asked to find the diameter or radius, given circumference or area. The correct 4-letter code will unlock the next puzzle.

My husband forwarded the Morning Brew newsletter to me this morning with this absolutely astounding story about Akira Haraguchi memorizing 100,000 digits of pi. 100 digits would be impressive, but 100,000?! The short article mentions him "mentally linking each digit with a syllable and creating a collection of epic stories from the words those syllables formed."😲

You probably already know that if you could fold a piece of paper 42 times the stack would reach the Moon. This always feels so unbelievable, but the math checks out! In this post, I want to share a couple handouts for students to support a discussion about exponential growth, folding paper to reach the Moon and also a few conversation starters.

Last summer, my daughter worked hard to learn her multiplication facts. Some facts she memorized, some she used strategies such as building on the facts that she already knew. For example, she adds one more number to her 11s to get to 12s. For 8 x 12, she multiplies 8 x 11 and adds 8. This was a multiplication strategy she completely taught herself.

Teaching the ins and outs of budgeting was one of my favorite units to teach in Consumer Math. It started with us calculating net monthly income and ended with us commenting on how much we all spend on food. It was a fun unit to teach because it gave students the tools to analyze their own spending and how it aligned with their future goals.

In our wages and salary unit, we learned that net monthly income is about 70% of gross monthly income. We often used this net income estimation when budgeting.
