Math games, especially in the primary grades, provide great opportunities for developing the number sense of young mathematicians. Working in pairs with a deck of single-digit cards, students take turns drawing two cards and reading the...

Second graders are asked to order two sets of two- and three-digit numbers from greatest to least, and then least to greatest.

Given three digits, what is the largest humber you can make? What is the smallest number you can make? These are the questions second graders are prompted to answer in a three-question quiz.

Scholars learn to divide multi-digit numbers using the standard algorithm in the 14th installment in a module of 21 parts. They get plenty of practice with the algorithm by completing a worksheet.

There are three money word problems in this activity, each one is set in the same context. The first asks what was the total amount grandma spent, the second how many grandchildren grandma has, and the third asks how much grandma spent...

Develop young mathematicians' understanding of place value with this hands-on math activity. Working in pairs, learners take turns building two-digit numbers by rolling two ten-sided dice. Base ten blocks are then used to model the...

Place value is a concept that sets a foundation for mathematical understanding. Ordering these sets of three- and four-digit numbers will help to strengthen that foundation. A great independent practice worksheet or short assessment to...

Boiling down any division problem to a one-digit divisor problem sure makes estimation easy. The lesson shows how to estimate division problems by using place value understanding and basic arithmetic facts to simplify the division. Some...

Do I have a right to make a copy? Head off this commonly asked question with this colorful, informative infographic, and promote digital citizenship in your class by directing learners to ask the right questions before...

Work it out — find the average time clients spend at a gym. Pupils use a table of random digits to collect a sample of times fitness buffs are working out. The scholars use their random sample to calculate an estimate of the mean of the...

In this digital age quiz, students respond to 10 true or false questions based on their opinions of gender bias in contemporary society.

Young mathematicians spin their way to a deeper number sense with this fun, collaborative activity. Using two spinners, one with the numbers 0-9 and the other with the decades 00-90, pairs of students take turns building and comparing...

When would you do multiplication on the floor? When you have no tables. Scholars determine a possible set of digits that would complete a 2-digit by 1-digit multiplication problem. They then determine all possible sets of digits and...

Can you spare a 10? Scholars determine digits that could complete a two-digit subtraction problem. They must find all possible combinations of digits and provide an explanation for their reasoning.

Learners are asked to make the largest three-digit number they can with the numbers 1, 8, and 5 in a quick assessment worksheet.

Know thy calculator. Young mathematicians use their calculators to answer a set of questions. They consider how the number of digits the calculator displays affects the answers to calculations. They then find examples of computations...

Mathematics involves a study of patterns. The exploratory lesson has learners consider the addition pattern in different sets of numbers. Each set has a different pattern that pupils describe mathematically. The patterns involve...

Help your class make sense of quantities and their relationships. Given is the product of two numbers. It is up to your number crunchers to think about the quantitative relationship when the product is one-tenth or ten times the product...

Math is all about finding patterns. In this ask, scholars first investigate a sequence formed by squaring the sum of the digits in the previous term. They go on to investigate a second sequence and write an algebraic expression for this...

Class members come up with a hypothesis on the number of decimal digits in the product of two decimals. Learners work in groups to complete several decimal multiplication problems. The results help groups develop a conjecture on the...

Support young mathematicians' interpretation of place value in order to multiply single-digit numbers by 10. The task builds upon and enhances a learners' understanding of place value, a second grade skill, while introducing...

Knowing math helps you win games. Learners apply conditional probability concepts in an engaging performance task. After playing a game in which players roll a 10-sided polyhedron and then try to place the digits to get the highest...

Goldilocks and the Three Numbers? The pre-activity task involves finding digits to complete decimals or fractions that satisfy given constraints, such as finding a fractions that is in between two others. The main task involves a similar...

An addition table supports third graders as they learn strategies to improve their math fluency. When finding sums greater than ten, young scholars are taught how to first make a ten and then add on the rest. A similar method is also...
