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, 4.OA.5
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.
