Unit 03
Energizers (5 min)
Below you will find a new spin on some energizers you may have already used in your classroom. Feel free to continue to use the other energizers listed in Unit 01 by clicking here: http://bit.ly/2evd1Dc.
I love math: two students, make a two digit number, multiply together. Students can use paper or dry erase markers to assist with multiplying.
Virtual Number Dice: Use the virtual number dice (single or double, if using double then call out make the greatest/least number possible) call out multiply by 10 or 100.

4.M.1 2-Digit by 2-Digit with Concrete, Array, Area Models, & Estimation (p.7-12)
In 4.M.1 Ramp Up, students use three different models to find the product of 2-digit numbers: base-ten blocks, arrays drawn on grid paper, and area models. Students also estimate the products before performing the operation. About the Problems: The numbers in these problems are especially chosen to make it easy to use base-ten blocks and to draw arrays and area models.

4.M.2 2-Digit by 2-Digit with Concrete, Array, Area Models, & Estimation (p.13-18)
In 4.M.2 Ramp Up, students use three different models to find the product of 2-digit numbers: base-ten blocks, arrays drawn on grid paper, and area models. Students also estimate the products before performing the operation. About the Problems: The numbers in these problems are deliberately chosen to make it easy to use base-ten blocks and to draw arrays and area models. The problems also require estimation.

4.M.3 2-Digit by 2-Digit with Area Models, Partial Products, & Algorithm (19-29)
In 4.M.3 Ramp Up, students begin to connect concrete models with abstract models as they estimate and solve 2-digit by 2-digit multiplication problems. They will use 3 different methods to solve problems: area models, partial products, and the standard algorithm. Students begin with the concrete as they draw area models and solve problems using partial products. Then they move toward an abstract understanding as they connect partial products to the standard algorithm.

4.M.4 2-Digit by 2-Digit Using Partial Products and Standard Algorithm
In 4.M.4 Ramp Up, students estimate and solve simple 2-digit by 2-digit multiplication problems using two methods: partial products and algorithms. Next, students test their problem solving skills as they analyze solutions to problems solved INCORRECTLY! Students must find the mistake that led to each wrong solution, explain it, and correct it.
About the Problems: Problem #2 requires students to know that there are 14 days in 2 weeks.

4.M.5 . 2-Digit by 2-Digit Using Partial Products & Arrays (p.35-38)
4.M.5 Ramp Up contains simple 2-digit by 2-digit multiplication problems. Each product is a perfect square so that students can see that multiplying a number by itself makes an actual square with models or drawings. And it’s the reason some numbers are called perfect squares or square numbers. Students will create models using base-ten blocks and then draw the models on grid paper, making a pictorial model. Note that 4.M.5 Ramp Up focuses on concrete models.

4.M.6 - 3-Digit by 1-Digit with Area Models, Partial Products, & Standard Algorithm (p.39-48)
In 4.M.6 Ramp Up, students continue to connect pictorial models with abstract models as they estimate and solve simple 3-digit by 1-digit multiplication problems. They will use 3 different methods: area models, partial products, and the standard algorithm. Students begin with the pictorial as they draw area models and solve problems using partial products. Then they move toward an abstract understanding as they connect partial products to the standard algorithm.

4.M.7 - 3-Digit by 1-Digit with Partial Products & Standard Algorithm (p.49-53)
In 4.M.7 Ramp Up, students estimate and solve simple 3-digit by 1-digit multiplication problems using partial products and other algorithms. Next, students test their problem solving skills as they analyze solutions to problems solved INCORRECTLY! Students must find the mistake that led to each wrong solution, explain it, and correct it.

4.M.8 -4-Digit by 1-Digit with Area Model, Partial Products, & Standard Algorithm (p.54-63)
In 4.M.8 Ramp Up, students continue to connect the pictorial and abstract as they use three different models to estimate the answers and solve simple 4-digit by 1-digit multiplication problems: area models, partial products, and the standard
algorithm.

4.M.9 - 4-Digit by 1-Digit with Partial Products & Standard Algorithm (p.64-68)
In 4.M.9 Ramp Up students estimate and solve simple 4-digit by 1-digit multiplication problems using partial products and other algorithms. Next, students test their problem solving skills as they analyze solutions to problems solved INCORRECTLY! Students must find the mistake that led to each wrong solution, explain it, and correct it. About the Problems: These problems tell a short story about a girl named Lucy Dynamic and her friends. On different problems, students calculate amounts for all 7 people, but, on other problems, they calculate for only some of them. Tell your students that they should read carefully. This kind of close reading is expected in STAAR for both math and ELAR.
