Sometimes dealing with decimals is so much easier than dealing with fractions. The ninth instructional activity in a 21-part module has the class consider situations when it might be easier to add or subtract fractions by first...

Introduces addition of decimals by using unit notation to represent the problem. Pupils use a place value chart to decompose the numbers and then add before connecting to the standard algorithm. 

Take a little bit away. The 10th section of an 18-part unit introduces subtraction of decimals. Scholars use a place value chart like they did with addition of decimals to organize and represent the problem. After using the place value...

See, decimal operations do come in handy! Pupils solve word problems that require adding, subtracting, multiplying, and dividing decimals. They use tape diagrams to express relationships and to identify the necessary operations to solve...

After discussing decimals and "going shopping" in the classroom, young mathematicians are given four practical word problems that require them to estimate their answers, given specific information. The highlight of the lesson...

Reinforce the concept of fractions and decimals as part of a whole with a lesson that begins with a mixed review, then goes into a three problem guided practice, and ends with a collaborative activity. The guided practice and activity...

Is it possible to add infinitely long decimals? As pupils complete the examples in the ninth lesson of this 25-part series, they determine that adding these decimals cannot be done without error. Their task is then to determine the size...

Become fluent in the language of mathematics. Scholars learn to divide multi-digit whole numbers and determine the most significant common factor and the least common multiple. They also investigate how to apply the distributive property...

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...

Sew up your unit on operations with decimals using this assessment task. Young mathematicians use given rules to determine the amount of fabric they need to sew a pair of pants. They must also fill in a partially complete bill for...

This unit on fractions allows for upper-aged elementary learners to explore ways to find the greatest common factor and least common multiple of two numbers. Ultimately, young mathematicians will be able to identify equivalent fractions,...
