Linear Measurement Week Four

Here's some background info on this Math main lesson block:

Linear Measurement & Coordinate Graphing - Intro

Linear Measurement Week Two

Linear Measurement Week Three

Here is what we did this week:

Day Ten

• what is another way that we could measure our gardens?
• explain the difference between perimeter and area as the difference between walking around the outside of a garden and going inside the fence, lying down on the ground, and doing snow angels everywhere
• do Area Differentiated Task Cards #1-24

  we pretended for the composite figures that one side of the garden was the Montagues and one side was the Capulets and they built a wall between them! we first calculated the area of each garden and then, when Romeo and Juliet fell in love and broke down the wall, we figured out the total area of the shape

  we also spent a lot of time on #23 since it has a missing quantity and cannot be solved as drawn (ultimately, we guessed a quantity and solved for the area using our guess, then looked in the answer key to see what she had, then went back and calculated what the missing quantity would need to be in order for her to arrive at her answer)

This week for extra practice at home, students worked on their Area and Perimeter Robot Craft. Each child was asked to do one robot using all perimeter OR all area, and one robot using both perimeter AND area.

Day Eleven

• have students calculate the area of their own gardens
• review the formula for the area of a rectangle and square; explain the formula for a right angle triangle (area is 1/2 of base ⋅ height) and how it is derived; explain the formula for the area of a circle (A=πr²)
  our gardens range from
  9.6 square inches
  12.57 square inches
  16 square feet
  194 square feet
  442 square feet
• ask students to consider the plants they want to plant and how much space each takes up
• research the area taken up by a plant by looking at how far they should be planted apart from one another using Cinder Block Gardens by Lynn Gillespie

  

• look at diagrams of how many plants can fit in a cinder block garden (having the garden bed be the same size in each diagram makes it really easy to compare the area each plant takes up) in chapter 13:
  carrots, p.150
  Swiss chard, p.156
  cucumber, p.160
  garlic, p.162
  kale, p.164
  lettuce, p.168
  melons, p.170
  onions, p.164
  potatoes, p.184
  pumpkin, p.186
  radish, p.188
  spinach, p.190
  summer squash, p.192
  tomatoes, p.198

• ask students to add their vegetables to their graph paper garden bed designs and color in the number of squares for the area taken up by each when full-grown; don't forget to color your path if you have one
• discuss other factors to take into account when planting such as soil requirements, light requirements, and companion plants
• watch How Trees Secretly Talk to Each Other ("The Wood Wide Web")

Day Twelve

• do Mrs. T's Raccoon Room (part 1)
• look at Geometric Cabinet Control Chart; identify the parallelogram

• discuss formula for the area of a parallelogram and how it originated; make a rectangle using the Geometric Stick Material and Working Board, then remove two nails, shift the angle, and replace the nails

• enjoy chanting "The Area Rhyme" to the tune of "Miss Mary Mack"
• share graph paper diagram of my 2020 vegetable garden and the companion plantings; use Louise Riotte's Roses Love Garlic and Carrots Love Tomatoes to look up the answers to student questions about companion plants for pumpkins, roses, and tomatoes

Day Thirteen

• have students share their scale garden drawings on graph paper and their Area & Perimeter Robots (these were a big hit!)
• do Volume and Perimeter Greeting Card Box Activity

  I modified the questions to only include three:
  What is the area of the top of the box?
  What is the volume of the box?
  Challenge Question: What is the surface area of the box?
