Three activities to help students with early math fluency: Quantity Discrimination (QD): The student is given a sheet of number pairs and must verbally identify the larger of the two values for each pair. Missing Number (MN): The student...

Students will practice counting on with this class game. The teacher will put multiple numbers in a hat or on sticks from the known counting sequence. S/he randomly picks one number and asks the class to count on ten numbers from that...

In this activity students can use the random number generator to generate numbers to make an expression using the correct order of operations when simplified will yield a target number.

In this activity, students explore the operations of addition and subtraction. They use estimation, a place value chart, and a calculator to place seven randomly generated numbers in the ones and tens position in a place-value chart to...

Imagine 31 numbers have been organized in ascending order in a list by a computer program. Now the program has to find a number in the list, but it can only look at one number at a time. Is it easier to find the number now, than if they...

This Khan Academy resource is an article about a game that gives you an idea of how different algorithms for the same problem can have wildly different efficiencies. The computer is going to randomly select an integer from 1 to 15....

In this interactive, use logic to solve riddles involving flea circus high jumps. Then, add two consecutive jumps and place them on a vertical number line. This often requires you to find equivalent fractions with common denominators....

In this interactive, use logic to solve riddles involving a flea-jumping contest. Place each contestant's jump, represented by either a fraction or a decimal in both feet and inches, at the correct point on the vertical number line....

Add money amounts under ten dollars. Numbers, not coins, are used in this activity. The decimals are lined up for you in the problem. There are ten random questions.

This activitiy asks students to randomly select a one-digit divisor and a three-digit dividend and estimate the quotient mentally. Students must then explain why they believe their estimate is accurate.
