Number Sense & Numeration
Grade 8: Number Sense & Numeration
Representing and ordering rational numbers; representing numbers using exponential notation; solving multi-step problems involving whole numbers and decimals; multiplying and dividing fractions and integers; multiplying and dividing decimals by powers of ten; applying order of operations in expressions with brackets and exponents; solving problems involving percents to one decimal place and percents greater than 100; solving problems involving rates and proportions.
Nature Journaling: I Notice..., I Wonder...?, It Reminds me of...
Nature Journaling is an incredible tool for helping students to add numeracy to their observations by making connections to numbers used everyday. Fractions can also be added by looking at an area and figuring what faction is covered in flowers, grass, a certain colour, etc. These can then be connected to decimal points and percentages.
At this age all three prompts "I notice..., I wonder...?, and "It reminds me of..." become very intuitive. However the statement "I wonder..." becomes very important at this age all the way up to 18 years as students deepen their understanding of the world around them. Encourage students to begin writing using single words, simple sentences, lists, point form, paragraphs and even poetry. Please note that spelling is not a focus in the nature journal. At this age you may start to see art fears - please ensure you are re-iterating it is not about a pretty picture. It is about their observations. Please see the link feedback at the bottom of this lesson for tips on this. Using words, pictures and numbers allows the students multiple tools to document their observations. With permission Bethan Burton has allowed us to link to her website as she has written a blog post for Teaching nature journaling at all ages.
Here are some more of Bethan's ideas to get you started.
Engage the fives senses (whenever possible)
Make leaf prints ( paint the leaf and press the print into the journal)
Make leaf rubbings
Trace the items they are looking at
Add leaves into the journal using tape
Count the birds/squirrels/insects etc.

GIVING FEEDBACK here is a fantastic resource from Jack and Emilie
NOTE: You are encourage to spend time in the outdoors Nature Journaling. However, you can also bring nature inside, look out your wonder window, have a refrigerator Safari or even observe a house plant or pet.
Nature Journaling: Comparison
In the activity Comparison from John (Jack) Muir Laws and Emilie Lygren's book: How to Teach Nature Journaling. "Students observe two objects in the outdoors (e.g. flowers, trees, rocks) and sketch them side by side, noting differences and similarities."

Planting - Comparing Rates
Once the plants start to sprout use standard units (mm, cm & m) to measure the height of the plants each day (or each week if there isn't growth to start).
Compare the height of the different plants you have planted (if available). If they are the same type of plant consider reasons for why they may be growing at different speeds. Document the different heights of each plant and determine the average growth and the percentage (showing both a fraction and decimal) of plants that are growing above and below this average height. Continue to document this for every week of growth.
Week to week, for each plant, determine the rate of growth compared to the average rate of growth.
