Learning Intention: Students will solve multiplication problems using 2 values whose product is less than or equal to 100; use concrete objects to prove the answer; use a calculator to prove the answer.
Success Criteria:Students will be successful when they can multiply by 1, 2, 3, 4, 5, 6, 7, 8, 9, and/or 10.
Essential Questions: - How can I make equal groups from this one large group? - How do I know this is a fair share? - What is the product? - How can I solve this multiplication problem using objects? - How can I solve this multiplication problem using a calculator?
Standards Covered
EE.6.NS.3. Solve two-factor multiplication problems with products up to 50 using concrete objects and/or a calculator. EE.7.NS.2.a. Solve multiplication problems with products to 100.
Multiplication is when you take one number and add it together a number of times.
Example: 5 multiplied by 4 = 5 + 5 + 5 + 5 = 20.
We took the number 5 and added it together 4 times.
This is why multiplication is sometimes called "times".
Repeated addition is adding equal groups together. It is also known as multiplication. If the same number is repeated then, we can write that in the form of multiplication.
Repeated addition is the easiest way to progress from additive to multiplicative understanding. It helps kids build rock solid mathematical understandings, compared to solving pages of multiplication problems. If this step is missed students will struggle with multiplication down the line.
