Students work in groups to figure out the answer to the Monty Hall Problem (you know, from Let's Make A Deal.. 2 goats, 1 car... ) You will need cards for each group: 2 number cards for the goats, 1 face card for the car. Basic probability and converting (fraction, decimal, percent) as well as critical thinking and reflection. I highly recommend finding a good Let's Make A Deal or Monty Hall YouTube video to show as an introduction for the activity. BUT - don't reveal the answer ahead of time!!

Help teach students the concept of adding and subtracting integers on a vertical number line with hot air balloons! Positive numbers are "air" - make the balloon go up Negative numbers are "sand" - make the balloon go down Addition - put the item(s) in the balloon Subtraction - take the item(s) out of the balloon Includes: -Directions -Problems to try together -Problems to try on their own (or in groups) -Patterns to look for and describe -Vertical number lines from -20 to 30 -Hot Air Balloon, A

A poster (or anchor chart, or handout, or desk card, etc.) about converting between fractions, decimals, and percents.

Probability activity: -tree diagrams -Fundamental Counting Principle -simple theoretical probability -critical thinking Students try to figure out the total number of the leprechaun's lucky lottery number possibilities and the probability of guessing it correctly. Could be done individually or in groups.

Good activity for introducing or practicing experimental probability. Starts with a Venn Diagram comparing theoretical and experimental probability. Then collecting, representing, analyzing, calculating data about M & M colors. *In case it's not obvious... you're going to need to provide M & M's for this to work. I have used 1 fun-sized bag per student or partner group; I have used 1 regular-sized pack per small group; I have also divided up BIG bags and distributed in cups or on napkins.

Guided notes sheet (1 page front/back) about Probability. Blank student copy and filled-in teacher copy included. Topics Include: -Outcomes & Events -Simple Probability -Experimental & Theoretical -Compound Probability -Independent & Dependent -

Using M & M's... -predict percentages -ratios of colors to total -convert to percentages using proportions -creating a bar graph -critical thinking and reflecting *In case it's not obvious... you're going to need to provide M & M's for this to work. I have used 1 fun-sized bag per student or partner group; I have used 1 regular-sized pack per small group; I have also divided up BIG bags and distributed in cups or on napkins.

2-page (or 1 front and back) guided notes page for adding and subtracting integers. Includes student copy with blanks and teacher copy filled in (examples are left up to you). Makes use of Keep Change Change (KCC) method for subtracting integers.

Graphic Organizer notes sheet about ratios, rates, and unit rates. Includes blank student copy and a sample completed teacher copy. I shared as a picture to my students' iPads and we completed it together on Sketches, but it can be used many different ways.

Graphic Organizer for the Inequality Symbols Fill in with names, definitions, examples, etc. Print the two pages front and back Cut on the small dotted lines Fold on the large dashed lines

A guided notes sheet (1 page front/back) Used for Percents unit: -Percent Proportion -Percent Equation -Percent Change -Percent Error -Discounts & Markups -Simple Interest
