However, this extension is problematic for many students, who start struggling with mathematics when fractions are introduced. Students should have a working understanding of terms: How many cookies are in each column? Another theory of learning multiplication derives from those studying embodied cognitionwhich examined the underlying metaphors for multiplication.
Some students might have counted by ones, others might have counted by threes, others may have counted by 5s. Where mathematics comes from: It is best to record this part of the lesson on chart paper because all students can see it easily and you can then post it around the room for future reference and use.
Connect to multiplication and explain, "Multiplication is another way to add equal groups. What are the guiding questions for this lesson? Draw a "garden" box a ten frame and ask students the guiding question "Where have you seen something like this before?
Instruct students to complete the worksheet independently. Retrieved 30 March General Lesson Plan Learning Objectives: I want you to tell me all of the number sentences for the following array: Is one answer correct or are both correct?

A part of the debate about multiplication and repeated addition is the comparison of different models and their curricular materials. Different models may or may not support multiplication of different types of numbers; for instance the set model  in which numbers are presented as collections of objects, and multiplication as the union of multiple sets with the same number of objects in each, cannot be extended to multiplication of fractional or real numbers.
You can write, create, any situational story of your choosing. So, we have 4 groups of 3.
Different models may also be relevant to specific applications of arithmetic; for example, combination models come up in probability and biology. Please login at the top of this page to access this resource.
