|Subject Area||Math and Science|
|Unit of Instruction||Addition and subtraction/word problems/rounding/forms of energy|
|Learning Targets and Learning Criteria|
• solve multi-step word problems (i.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, standard algorithm for addition and subtraction, 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 prior to calculation.
• apply an understanding of addition and subtraction, place value, and flexibility with multiple strategies to use the standard algorithms for addition and subtraction.
• 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.
