Challenge 4th graders to move beyond and apply their initial understanding of multiplying one- and two-digit numbers to word problems that have three- and four-digit numbers. The worksheet covers essential questions, task description, task directions, formative assessment questions, and possible student solutions, all of which make this resource a practical application of the Common Core standards. It is easy to understand and ready to use in the classroom.
Students practice the use of number properties through exploring the difference of two squares, creating an array model for multiplication, and work with decimal numbers. In groups, students explore patterns in an array and determine algebraic reasoning to explain the pattern.
Fourth graders practice mastering the ability to multiply multi-digit numbers utilizing rectangular arrays and a variety of mental math strategies. They model and illustrate meanings of multiplication and division of whole numbers and the addition and subtraction of fractions.
Students design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme activity. Students are expected to predict how one of the factors might affect the reaction rate and test it in a high quality experiment.
How to use the relationship between multiplication and division to solve math word problems is the focus of the lesson presented here. In it, fourth graders work in groups to solve problems posed by the teacher. Then, each group is given paper cups and uses them as a manipulative to solve another problem. Finally, each group completes the problems on a worksheet entitled, "What to do with Remainders," and shares their results with the class. Other terrific worksheets are embedded in this fine plan.
Third graders begin learning about multiplication using arrays. In this multiplication with arrays lesson plan, 3rd graders interact with tiles on the overhead as they follow the teacher in making arrays. They write multiplication sentences based on the arrays and complete an assessment by show arrays on geoboards.
Sixth graders explore probability through experiments using lists, arrays, tree diagrams, and station games. In this theoretical probability instructional activity, 6th graders use a tree diagram to find probable outcomes in an experiment. Students then rotate through stations, playing theoretical probability games. Students determine if the games are fair or biased.
Enhance and support your pupils' thinking about multiplication with two tasks centered around arrays. This worksheet provides opportunities for learners to use numbers and words to explain their thinking. It can be used as a part of a homework assignment, in-class assignment, or exit ticket. Note: This is the last of three writing tasks. See additional materials for links to the previous two.
