Four different-shaped and dyed pasta types represent four different alleles. Following a guide sheet, young geneticists practice randomly selecting alleles and discover the traits of the resulting offspring. This is a fun and solid...

Can't read this now, I'll have to check it out later. A teacher's time is always limited. So often as we peruse the web for personal and professional content, we come across sites and information that we cannot immediately...

Young scientists create monsters by applying their knowledge of transcription and translation. They randomly find the DNA, assign it a codon, and build monsters piece by piece. 

Young mathematicians define population, draw convenience sample from the population, draw quota sample from the population, and draw random probability sample from the population. They explain why a random probability sample usually...

Learn how to determine a probability distribution. In the ninth installment of a 21-part module, future mathematicians use theoretical probabilities to develop probability distributions for a random variable. They then use these...

Do your writers have a hard time properly citing their sources in MLA style? Use this SMART board activity to practice these skills in a fun, interactive way. After debating a topic in class (the lesson uses "random drug testing in...

Investigate expected value as a long-run average. The eighth installment of a 21-part module has scholars rolling pairs of dice to determine the average sum. They find aggregate data by working in groups and interpret expected value as...

Learners conduct a simulation to explore how scientists estimate the size of animal populations. They analyze a random sample and then extrapolate those results to a larger population. Additionally, they will apply the principals of...

Youngsters develop their number sense by rote counting from one to ten. Over time, they identify the numbers on their own and no longer rely on fixed recitation. Using numerical flashcards, a teacher will randomly choose numbers from the...

A jar is filled with 1,500 marbles and customers of a bank can enter a contest to guess the correct percentage of blue marbles. How can an employee at the bank estimate the actual percentage without physically counting all 1,500 marbles?...

Assess whether your kindergartners can identify numbers in random order using two sets of numeral cards 1-10 and 11-20. Starting with a small group and the 1-10 deck give your learners the task of putting the cards into order from...

Using a number line or a 100s chart that extends past 100, practice counting from 1 to 120 with your class. As a part of daily instruction, chant count in sequence from 1 to 100 and then randomly chose a number and count onward to 120....

The pupils practice modifying parameters in a function to add variations to their under the sea scene. The resource also introduces random number functions that alter the scene every time the program runs.

Winning a spin game is random chance, right? Pupils create a table to determine the sample space of spinning two spinners. Individuals determine the probability of winning a game and then modify the spinners to increase the probability...

Scholars learn how to crack secret codes as they continue reading from the Blown to Bits and try to crack the random substitution cipher. They also begin learning about the Vigenere cipher. 

Review the vocabulary from The Odyssey with this fun "I Have, Who Has" game. First, give students random vocabulary cards (included) that say "I have (vocabalary word). Who has (definition of another vocabulary word)?" Students are...

Seventh graders explore random sampling by estimating the number of e's on the newspaper. They explain the possible error sources for this type of sampling, and compare the accuracy of sampling a small and large population. This is a...

What is the probability that two randomly seated people will be across from each other at a square table? Check learners' understanding of theoretical probability and compound events with this short assessment. A great opportunity to...

If a random sample determines that 45% of students favor block scheduling, is it possible that the actual percentage might be 50% or 60%? In this task, learners use data from a computer-generated simulation to determine the plausibility...

Can I say a number by its name, and can you write it for me? Working in small groups or with the whole class, give your kindergartners a piece of 1-inch graph paper and have them write numbers 0 to 10 and 11 to 20. Next, pass out blank...

Working in pairs, young mathematicians will practice number identification with a game of tic-tac-toe. Supplies needed: two 3x3 grids with numbers 1-9 in random order, and two different colored crayons. Player 1 will choose and read a...

Your student programmers will enjoy creating their own Magic 8-ball in this JavaScript activity. This a great opportunity to practice using if and else statements based on randomly generated numbers. What will you ask the 8-ball? 

In this probability worksheet, students solve 2 different problems that include 7 parts in the first one and 2 parts in the second. First, they find the probability that one marble selected at random from a jar will be yellow or green....

Learners explore how to select unbiased random samples as they choose report data to include on maps. They propose methods for choosing random numbers and discuss their advantages and disadvantages. They consider bias in science.
