3 x 3 Vocabulary Challenge

(View Complete Item Description)

3 x 3 Vocabulary Challenge Use within any subject Need a bank of at least 10 words from a similar subject. Students will put 9 words randomly in the 3x3 grid. Challenge: Make a sentence using each word in row 1. Challenge students to make sentences for each row and column in the 3x3 grid. Can be done collaboratively, or individual. Nice to mix it up!

Acquiring New Vocabulary Through Book Discussion Groups

(View Complete Item Description)

In this lesson, students read Pink and Say by Patricia Polacco to identify words that are unfamiliar to them. Working collaboratively in small groups, they discuss the meaning of these new words, using context clues from the text, prior knowledge, and both print and online resources. Students then apply their knowledge of the new vocabulary to further their understanding of the text.

Constructing Diagrams of Food Chains

(View Complete Item Description)

In this activity, students will use color-coded cards to represent different types of organisms in an ecosystem and model food chains to show the relationships between organisms. Students will also analyze simple scenarios and discuss consequences of change in the ecosystem.

Be There or Be Square

(View Complete Item Description)

The purpose of this task is for students to connect the completing the square procedure learned in the previous two tasks to graphing parabolas. The task asks students to complete the square to change the equation of a quadratic function in standard form into vertex form. Students will need to extend their understanding of completing the square in an expression to an equation to maintain the equality, requiring that they add and subtract an equivalent term to one side of the equation (effectively adding zero) or that they add the same thing to both sides of the equation. After getting the equation into vertex form, students graph the equation of the parabola.

Building the Perfect Square

(View Complete Item Description)

The purpose of this task is to develop students’ understanding of the procedure of completing the square using area models. In the task, students will use diagrams of area models to make sense of the terms in a perfect square trinomial and discover the relationship between coefficients of a quadratic expression. They will use this understanding to complete the square to find equivalent forms of quadratic expressions. In this task, the quadratic expressions will be limited to those in which the coefficient of the !! term is 1. This task is the beginning of a learning cycle that ends in students using the completing the square procedure to find the vertex form of a quadratic function and graph the associated parabola.
