LZ Unit 4 Lesson 3

LZ Unit 4 Lesson 3

by Javier Valera

​Remember?

​

​Yesterday we matched situations with diagrams and...

​

​... we wrote equations of those diagrams.

Today...​

You will match situations, equations and diagrams!

​

​On the next slides you will match 1 equation and 1 diagram for each situation.

Multiple Select

Noah ate $$x$$  ounces of blueberries, and Elena ate $$\frac{1}{3}$$  less than that.

Select the equation AND the diagram that represent the situation.

• $$y\ =\ \frac{2}{3}x$$  

• $$y\ =\ \frac{1}{3}x$$  

Multiple Select

Elena biked $$x$$  miles and Noah biked $$\frac{2}{3}$$  more than that.

Select the equation AND the diagram that represent the situation.

• $$y\ =\ \frac{8}{3}x$$  

• $$y\ =\ \frac{5}{3}x$$  

Multiple Select

Elena danced as long as Noah danced, $$x$$   and then she danced that same amount again.

Select the equation AND the diagram that represent the situation.

• $$y=2x$$  

• $$y=\frac{1}{2}x$$  

Multiple Select

Noah saved $$x$$  dollars, and Elena saved $$\frac{1}{10}$$  less than that.

Select the equation AND the diagram that represent the situation.

• $$y\ =\ \frac{1}{10}x$$  

• $$y\ =\ \frac{9}{10}x$$  

Multiple Select

Noah bought $$x$$  pounds of apples, and Elena bought $$\frac{1}{4}$$  less than that.

Select the equation AND the diagram that represent the situation.

• $$y\ =\ \frac{5}{4}x$$  

• $$y\ =\ \frac{3}{4}x$$  

Multiple Select

Elena swam $$x$$  laps in the pool, and Noah swam $$\frac{2}{5}$$  less than that.

Select the equation AND the diagram that represent the situation.

• $$y\ =\ \frac{2}{5}x$$  

• $$y\ =\ \frac{3}{5}x$$  

Multiple Select

Elena ate $$x$$  pretzels, and Noah ate $$\frac{1}{3}$$  more than that.

Select the equation AND the diagram that represent the situation.

• $$y\ =\ \frac{4}{3}x$$  

• $$y\ =\ \frac{1}{3}x$$  

Multiple Select

Noah ran $$x$$  kilometers, and Elena ran $$\frac{3}{10}$$  more than that.

Select the equation AND the diagram that represent the situation.

• $$y\ =\ \frac{13}{10}x$$  

• $$y\ =\ \frac{3}{10}x$$  

Draw

Draw a diagram that represents the situation: Diego drank 𝑥 ounces of juice. Lin drank 1/4 less than that

Draw

Draw a diagram that represents the situation: Lin ate 𝑥 ounces of pie. Diago ate 1/2 more than that

AWESOME JOB!

How well do you understand situations, equations and diagrams of increases and decreases?

• I am a master!

• Kind of good

• So and so

• Uh? No idea!
