In this lesson, students will demonstrate the commutativity of multiplication, and practice related facts by skip-counting objects in array models.

In this lesson, students find related multiplication facts by adding and subtracting equal groups in array models.

In this lesson, students interpret the quotient as the number of groups or the number of objects in each group using units of 3.

In this lesson, students skip-count objects in models to build fluency with multiplication facts using units of 4.

In this lesson, students relate arrays to tape diagrams to model the commutative property of multiplication.

In this lesson, students learn how to apply the distributive property to decompose units for multiplication.

In this lesson, students learn how to solve two-step word problems involving multiplication and division, and assess the reasonableness of answers.

In this lesson, students learn how to solve two-step word problems involving all four operations, and assess the reasonableness of answers.

Students determine the coefficient of restitution (or the elasticity) for super balls. Working in pairs, they drop balls from a meter height and determine how high they bounce. They measure, record and repeat the process to gather data to calculate average bounce heights and coefficients of elasticity. Then they extrapolate to determine the height the ball would bounce if dropped from much higher heights.

How many sodas are there on a Coke Freestyle machine? Students can use a variety of problem solving skills to make combinations of flavors that would come from one soda machine. These are questions asked to start the lesson:
What is a guess that you know is too low?
What is a guess that you know is too high?
Does anyone else have the same answer but another way to explain it?
What other strategies could we have used to figure out how to count them?
Includes a video link, flavor list, and standards K-3 that can be altered or modified depending on lessons being taught.

I want to use technology in a really useful way to make my math groups that would give me time to teach and support directly to my small groups and individuals.

I made a Google Form (Google Forms: https://www.google.com/forms/about/) for our district approved curriculum called Everyday Math (https://connected.mcgraw-hill.com/connected/login.do) Unit 2- Solving number stories.   The pre/post test is 8-10 questions on the main teaching points from the Unit. The feedback from that would help me make my small groups before I start teaching the lesson.

I will use Google Classroom for each math group (or one main Classroom that I share through to each group) that I can push out work to for their practice after the whole group math lesson each day.  It would function as a digital way of organizing and showing groups what they are doing, instead of the normal pocket chart or posted schedule in the classroom.  This gives me more flexibility on changes throughout the week, and the ability to link in any online resources.

Small group work could consist of journal pages, hands-on game, IXL practice (IXL.com), links to Khan Academy lessons (khanacademy.com), Nearpod lessons/practice (nearpod.com), as well as many other math support websites, apps or hands-on practice.  Groups would also meet with me throughout the week as part of the rotation (lower groups more often), but having small group activities ready to go will give groups who are not with me the independence to get work done effeciently each day. At the end of the unit, students will then take the same test, as a post-test to show growth.

I like the idea of doing this because if gives me an idea of where my students are before I start the unit.  Using a pre-made, short form helps making the groups an easy process.  Having a pre-made list of resources, helps make group work productive and successful.

Students will determine the unknown factor in a division equation in tihs two-player game. They will take turns choosing a number card 1-10 until they find a factor that completes the unknown of the division equation. This activity can be used during small group instruction and later moved into a center activity to assist students master division facts. It includes four sets of division cards.

In this lesson students build tables and use patterns as an introduction to multiplication. They are encouraged to use multiplication by 10 or 100 for larger values as the beginnings of commutativity and distribution are introduced.
