MAFS.4.OA.1.3, MAFS.4.NBT.2.4 (not fluently), MAFS.4.MD.1.2 (only whole numbers), MAFS.4.OA.1.a and MAFS.4.OA.1.b (Number Talks)
- Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
- Add and subtract multi-digit whole numbers using the standard algorithm.
- Use the four operations to solve word problems involving distances, intervals of time, money, and intervals of time using linear models.
- Determine whether an equation is true or false by using comparative relational thinking. For example, without adding 60 and 24, determine whether the equation 60 + 24 = 57 + 27 is true or false.
- Determine the unknown whole number in an equation relating four whole numbers using comparative relational thinking. For example, solve 76 + 0 + n + 5 for n by arguing that nine is four more than five, so the unknown number must be four greater than 76.
- Identify common materials that conduct heat well or poorly.
- Recognize that heat flows from a hot object to a cold object and that heat flow may cause materials to change temperature.
- Explain how weather impacts Florida.
- Solve multi-step word problems (e., up to 3 steps) that involve the four operations using strategies for this grade level (e.g., rectangular arrays, area models, properties of operations, etc.).
- Represent a multi-step word problem using equations involving a variable represented by a letter for the unknown number.
- Interpret remainders that result from multi-step word problems.
- Assess the reasonableness of answers to multi-step word problems using estimation strategies and mental computation.
- Use the four operations to solve word problems involving money including whole numbers only.
- Apply an understanding of addition and subtraction, place value, and flexibility with multiple strategies to use the standard algorithms for addition and subtraction.
- Use the four operations to solve word problems involving intervals of time including whole numbers only and represent the intervals of time using linear models.
- Determine if a given equation is true or false by comparing, composing, and/or decomposing the numbers without solving.
- Compare the two sides of an equation to determine the unknown value without solving.
- Review how things that give off light often give off heat.
- Review how heat is produced when two objects rub against each other.
- Investigate heat energy by measuring temperature changes in a liquid.
- Compare observations with classmates explaining any differences that occur.
- Collect and record temperature readings during investigations in charts, tables, and graphs.
- Investigate which materials are the best conductors of heat (e.g., clay, metal, and glass).
- Investigate which materials are non-conductors/insulators of heat (e.g., plastic, wood, Styrofoam).
- Make inferences about observations made during conductivity investigations.
- Form conclusions about which materials conduct heat well or poorly based on investigations.
- Investigate and diagram the direction of heat flow (hot cold).
- Record observations of heat transfer (in the form of temperature changes) within tables, charts, and graphs.
- Analyze and form conclusions based on their recorded observations and data.
- Describe Florida’s weather patterns by season. Examples may include, but are not limited to, hurricanes, thunderstorms, drought, frost, mild climate.
- Describe the impacts of Florida’s storms, including hurricanes and thunderstorms.
- Explain the economic, architectural, scientific, and social impacts weather has on Florida.
