Standard(s) Taught

Math:

MAFS.4.OA.1.3, MAFS.4.NBT.2.4, MAFS.4.MD.1.2(Whole Numbers Only)4.OA.1.a and 4.OA.1.b

1.     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.

2.     Use the four operations to solve word problems involving distances, intervals of time, and money, including problems involving simple fractions or decimals. Represent fractional quantities of distance and intervals of time using linear models.

3.     Fluently add and subtract multi-digit whole numbers using the standard algorithm.

4.     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.

5.     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.

Science: SC.4.P.10.1, SC.4.P.10.3

 1.     Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion.   2.     Investigate and explain that sound is produced by vibrating objects and that pitch depends on how fast or slow the object vibrates.
Learning Targets and Learning Criteria

Math:

1. 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, etc.).
2. Represent a multi-step word problem using equations involving a variable represented by a letter for the unknown number.
3. Interpret remainders that result from multi-step word problems.
4. Assess the reasonableness of answers to multi-step word problems using estimation strategies and mental computation.
5. Use the four operations to solve word problems involving money including whole numbers only.
6. Apply an understanding of addition and subtraction, place value, and flexibility with multiple strategies to use the standard algorithms for addition and subtraction.
7. Determine if a given equation is true or false by comparing, composing, and/or decomposing the numbers without solving.
8. Compare the two sides of an equation to determine the unknown value without solving.
9. Use the four operations to solve word problems involving distances (i.e., inch, feet, yard, mile; millimeter, centimeter, meter, kilometer), including problems that require expressing measurements given in a larger unit in terms of a smaller unit, involving whole numbers only.

Science:

1. Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion (mechanical).
2. Identify examples of these energy forms in their life and in the natural world.
3. Compare and contrast these types of energy.
4. Review how light travels in a straight path until interrupted by an object.
5. Review how light passes through other objects (transparent, translucent, opaque).
6. Review how light reflects, bends, and absorbs.
7. Investigate the production of sound (e.g., tuning forks, hollow tubes, vocal cords, or water bottles filled with different amounts of water).
8. Explain that sound is produced by vibrating objects.
9. Investigate variations in pitch (e.g., water bottle liquids, rulers, straws, stretched rubber bands).
10. Explain that pitch depends on the speed (fast and slow) an object vibrates and the measurements (size and length) of the object.
