The instructions say that to ice 1 batch of cupcakes with aqua-colored icing, we will need 2 drops of green food coloring and 5 drops of blue food coloring. How many drops will we need for 1 batch, 2 batches, 5 batches, etc. (Record in a table.)]]> 2021-10-30 19:18:31 UTC https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855842554 tlsavage2 https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855845426 A ratio is a number that relates two quantities or measures within a given situation in a multiplicative relationship.]]> 2021-10-30 19:21:53 UTC https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855845426 tlsavage2 https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855846222 2021-10-30 19:22:51 UTC https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855846222 tlsavage2 https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855848761 A ratio can relate one part of a whole (9 pink fish) to another part of the same whole (7 blue fish). This is represented as 9/7.

The number of girls in a class (9) to the number of students in the class (16) this can be written as 9/16, or can be thought of as nine-sixteenths of the class. Percentages and probabilities are examples of part-whole ratios.]]> 2021-10-30 19:42:44 UTC https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855862028 tlsavage2 https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855865286 Ratios can be thought of as quotients. Fr example, if you can buy 4 kiwis for $1.00, the ratio of money for kiwis is $1.00 to 4 kiwis, or 1/4, and is a quotient. Diving the values results in $0.25 for one kiwi, the unit rate.]]> 2021-10-30 19:46:56 UTC https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855865286 tlsavage2 https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855869420 Rates involve two different units an how they relate to each other (ex. miles per gallon, square yards of wall coverage per gallon of paint). Relationships between two units of measure are also rates (ex. inches per foot, centimeters per inch). A rate represents a infinite set of equivalent ratios. ]]> 2021-10-30 19:52:12 UTC https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855869420 tlsavage2 https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855874868 (Use tape diagrams.) For every 3 bass that are put in a pond, Edwin puts 8 blue gill in the pond. If (or Assume) Edwin puts 24 blue gill in the pond, how many bass does he need to put in the pond.
Ask questions such as:
What fractional part is the bass compared to the blue gill? (3/8)
What fractional part is the blue gill compared to the bass? (8/3)]]> 2021-10-30 19:59:15 UTC https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855874868 tlsavage2 https://padlet.com/cmdivins/4ta2yqydiu5auvub/wish/1855885129 This can help with proportional reasoning.
