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...

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...

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...

Deep mathematical thinking is found with just a coin and a number line. Combining computing some probabilities in a discrete situation, and the interpretation of a function, this simple task gives learners a lot to think about on...

In need of math station or center for your kindergartners? Model how to play this game with the whole class first and then make it into a center. Create a few sets of six number cards with 0-5 or 5-10 and then create a matching die with...

Practice sequencing numbers 1–100 in a card sequencing activity. The hands-on learning makes a short activity flexible and fun. The opportunities are endless and easy to implement.

Your statisticians draw several samplings from the same data set, some randomized and some not, and consider the distribution of the sample means of the two different types of samplings. The exercise demonstrates that non-random samples...

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....

Get the whole class involved in practicing their multiplication facts with this fun collaborative activity. With each child given a card containing both a product and an unrelated multiplication sentence, the activity begins as...

if you've ever had to guess how many items were in a jar, then this problem is for you! With a big jar full of red and white marbles, does picking a sample of 16 allow your learners to get a good estimate on the percentages of each...

Young mathematicians concentrate on learning to fluently count. Following the rules of the classic game Memory, children take turns flipping over cards in order to find pairs of numbers that cross a decade (e.g. 29 and 30). For younger...

High schoolers investigate the greenhouse effect and examine the potential effects of climate change in the Arctic. They construct a mini-greenhouse and test its effect on temperature, analyze historical climate statistics, and conduct...

A great aspect of teaching math is that children have the freedom to solve problems using a variety of different strategies. The focus of this lesson is for young mathematicians to become aware of many ways of answering addition...

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? 

Can multiple computers sort a list faster than one? Using a network drawn with chalk outside, groups move through the decision network to sort numbers. A series of extension questions come with the lesson and can be used in the same...

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...

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,...

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...
