Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.

xpmath.com (pick 'medium')

Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921,without having to calculate the indicated sum or product. Generate two numerical patterns using two given rules. Identifyapparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane.

Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.

Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.

Read and write decimals to thousandths using base-ten numerals, number names, and expanded form, e.g., 347.392 = 3 × 100 + 4 × 10 + 7 × 1 + 3 × (1/10) + 9 × (1/100) + 2 × (1/1000).

Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.

Half Court Rounding (3 pointers)

Fluently multiply multi-digit whole numbers using the standard algorithm.

Batter's Up Baseball (pencils)

Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.Online Division Practice (use paper and pencil)

Scored Practice (use paper and pencil)

Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.

EZ Fractions (mrnussbaum.com)

Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.

Apply
and extend previous understandings of multiplication and division
to multiply and divide fractions.

Interpret
a fraction as division of the numerator by the denominator (a/b =
a ÷ b). Solve word problems involving division of whole numbers
leading to answers in the form of fractions or mixed numbers, e.g.,
by using visual fraction models or equations to represent the problem.
Interpret division of a unit fraction by a non-zero whole number, and compute such quotients. For example, create a story context for (1/3) ÷ 4, and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that (1/3) ÷ 4 = 1/12 because (1/12) × 4 = 1/3.

Interpret division of a whole number by a unit fraction, and compute such quotients. For example, create a story context for 4 ÷ (1/5), and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that 4 ÷ (1/5) = 20 because 20 × (1/5) = 4.

Solve
real world problems involving division of unit fractions by non-zero
whole numbers and division of whole numbers by unit fractions, e.g.,
by using visual fraction models and equations to represent the problem.
For example, how much chocolate will each person get if 3 people
share 1/2 lb of chocolate equally? How many 1/3-cup servings are
in 2 cups of raisins?

Convert
among different-sized standard measurement units within a given
measurement system (e.g., convert 5 cm to 0.05 m), and use these
conversions in solving multi-step, real world problems.

Make
a line plot to display a data set of measurements in fractions of
a unit (1/2, 1/4, 1/8). Use operations on fractions for this grade
to solve problems involving information presented in line plots. For
example, given different measurements of liquid in identical beakers,
find the amount of liquid each beaker would contain if the total amount
in all the beakers were redistributed equally.
Geometric
measurement: understand concepts of volume and relate volume to
multiplication and to addition.

Recognize
volume as an attribute of solid figures and understand concepts of
volume measurement.
e.g., to represent the associative property of multiplication. Apply the formulas V = l × w × h and V = b × h for rectangular prisms to find volumes of right rectangular prisms with whole number edge lengths in the context of solving real world and mathematical problems. Play

Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles. Quadrilateral Warfare Classify two-dimensional figures in a hierarchy based on properties.
