Metric System

Objectives: Today I will be able to: Understand the size and numerical relationship between the units in the metric system Informal assessment – monitoring student interactions as they complete the warm –up, category sort and scavenger hunt Formal assessment – analyzing student responses to the exit ticket and the price is right activity Common Core Connection Model with mathematics Look for and make use of structure

Lesson Sequence Evaluate: Warm-Up Explain: Metric System Notes Engage/Explore: Metric System Category Sort Explore/Elaborate: Metric System Scavenger Hunt Engage/Evaluate: Price Is Right Evaluate: Exit Ticket

Warm – Up (Day 1) Complete the “Estimation 1” column on the metric system warm up worksheet

Warm – Up (Day 2)

Objectives Today I will be able to: Understand the size and numerical relationship between the units in the metric system

Homework Study for the significant figures quiz on Thursday, September 11

Agenda Warm Up Metric System Notes Category Sort Activity Metric Scavenger Hunt Price is right Exit Ticket

Metric System aka International System of Units (SI System)

Why do we use the metric system? Easy to use mathematically More divisions – improves accuracy of measurements Used internationally – easier to communicate

There are 7 base units Length = meter (m) Mass = kilogram (kg) - Gram is commonly used (g) Time = seconds (s) Temperature = Kelvin (K) Count/Quantity = mole (mol) Electric Current = ampere (A) Luminous Intensity = candela (cd)

Prefixes Giga (G) – 10 9 Mega (M) – 10 6 Kilo (k) – 10 3 Hecto (h) – 10 2 Deka (D) Base Unit – 1 Deci (d) – Centi (c) – Milli (m) – Micro (u) – Nano (n) – Pico (p) –

Metric Mneumonic Kids Have Dropped Over Dead Converting Metrics K = Kilo H = Hecto D = Deka O = One (base unit) – 1 gram, 1 liter, 1 meter D = Deci C = Centi M = Milli

Metric Category Sort Activity

Directions

Metric Scavenger Hunt Work in a small group to find objects that fit into the categories. We will have a class discussion about the answers

Price is Right Follow Ms. Ose’s Directions for the game

Exit Ticket (1) Complete the “estimation 2” column on the metric system warm up/ exit ticket worksheet We will discuss any changes that you made to the values listed Icebreaker If you could go back in time and change one thing, what would you change? Would you rather have to carry an egg (and not let it break), or wear a motorcycle helmet, everyday for the rest of your life ?

Exit Ticket (2) Icebreaker Would you rather live in an igloo or a teepee? Would you rather be the smartest person in the world or the richest person in America?
