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.

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...

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?...

Using a number line, as a class, discuss the concept of the number after. Choosing numbers on the number line, ask your kindergartners what number comes next and point to that number. Once the class has this concept down, pair-up and...

Here is a great problem-solving activity for young mathematicians. Intended solely for instructional purposes, the activity is appropriate for learners to add four numbers together. Not only must they add four numbers together,...

Practice counting forward and completing number sentences with this four-part instructional activity. Learners start by completing three number sequences, filling in the first number. Then, they switch it around by finishing two number...

Young mathematicians are on their feet and moving around in this primary grade sorting activity. After giving each child an object or picture card, they then sort themselves into groups, counting to see which has the most or least...

I can find the error in an array of cards? After watching a demonstration class members search for the error is the provided cards. The resource provides a real-life example of using ISBN numbers in error detection and using check...

A little bit complicated, but a whole lot of fun. Show your class an episode of the British television game show Just a Minute. After an explanation of the rules (no repetition, hesitation, or deviation) groups develop topics, based on...

Games are great for reinforcing key skill sets and providing fun practice. Here are two games complete with printable materials and instructions. Children will play consonant digraph Jeopardy and digraph concentration using the same set...

Intended as a follow up to the Protecting Your Drinking Water activity, young environmentalists use their assessment of the a hypothetical town's water supply to debate the installation of underground chemical storage tanks. With...

The probability of learning from this lesson is high! Learners calculate probabilities as numbers and as decimals. They see how to use a complement to find a probability and even try a simple geometric probability problem.

The way you use statistics can tell different stories about the same set of data. Here, learners use sets of data to determine which person sends the most text messages. They use random sampling to collect their data and calculate a...

Learners participate in probability experiments and simulations while modeling and solving problems. They examine how to use the random number generator on a graphing calculator using examples from their local hockey teams.

Young scholars implement rules for adding, subtracting, dividing, and multiplying negative integers. They write rules for each mathematical operation of negative numbers. In groups, students complete number operations. Using PDAs, they...

In this skip counting worksheet, learners complete a table by counting by 2. Five random numbers are already filled in for students. A website reference for additional resources is given.

In this probability worksheet, 8th graders solve and complete 10 different problems that include word problems and probability. First, they determine the probability that the value of a roll will be less than a particular number. Then,...

Students examine uses for ordinal numbers in calendars, and an ordinal chart. They order ice cream cone cut outs from 1st to 20th and complete a worksheet. (not given)

What makes a good sample? Your classes collaborate to answer this question through a task involving areas of rectangles. Given a set of 100 rectangles, they sample a set of five rectangles to estimate the average area of the figures. The...

You've heard of a pie graph, but what about a pizza pie graph? Challenge young mathematicians to answer ten questions based on a random survey of people's favorite pizzas. A pie graph displays the percentages of each type of pizza. Some...

This is a quick learning game that can be played on a daily basis during transitions or as a part of the morning meeting. Using number cards or numbers placed on sticks, pick a number at random. Read the number to the class and then ask...

A simple counting activity to help your kindergartners count in sequence. Hand out number cards randomly (one to represent each child in your class) to each class member. Now ask the class to put themselves in sequential order beginning...

Students gather appropriate information for simple statistical analysis. Then they will calculate probability working with a piece of literature that makes this instructional activity ideal for teaching across the whole curriculum.

Middle-schoolers solve linear equations with one single variable. They solve equations that are randomly generated using index cards. Half of an equation is written on each card and distributed to the class. which then attempts solve...
