Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each.

Picnic Multiplication (Sheppard)

Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each.Division Bingo (Missing Quotients)

Understand properties of multiplication and division and the relationship between multiplication and division.

Harcourt Multiplication Practice (Pick Multiplication, facts up to 10)

Solve two-step word problems using the four operations. 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.Mystery at The Peculiar Zoo (x,÷)

The Big Top Carnival Caper (x,÷)

Identify
arithmetic patterns (including patterns in the addition table
or multiplication table), and explain them using properties of
operations. *For example, observe that 4 times a number is
always even, and explain why 4 times a number can be decomposed
into two equal addends.*

Use place value understanding to round whole numbers to the nearest 10 or 100.

Half Court Rounding (play for 1 point & 2 points)

Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.

Multiply one-digit whole numbers by multiples of 10 in the range 10–90 (e.g., 9 × 80, 5 × 60) using strategies based on place value and properties of operations. Multiplication Slot Machine (xpmath.com)

Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.

Understand a fraction as a number on the number line; represent fractions on a number line diagram.

Fractions on a Number Line (thatquiz.com)

Play
*The Ruler Game* (pick eighths)

Represent a fraction 1/b on a number line diagram by defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line.

Represent a fraction a/b on a number line diagram by marking off a lengths 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.

Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size. Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line. Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3). Explain why the fractions are equivalent, e.g., by using a visual fraction model.Simplify Fractions (thatquiz.com)

Online Fraction Bars (mathplayground.com)

Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers.Compare
two fractions with the same numerator or the same denominator by
reasoning about their size. Recognize that comparisons are valid
only when the two fractions refer to the same whole. Record the
results of comparisons with the symbols >, =, or <, and justify
the conclusions, e.g., by using a visual

fraction model.

Solve
problems involving measurement and estimation of intervals of time,
liquid volumes, and masses of objects.

Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.

Elapsed Time Matching(quia.com)

Time For a Crime (Problem Solving)

Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l).6 Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.

Geometric
measurement: understand concepts of area and relate area to multiplication
and to addition.

Recognize
area as an attribute of plane figures and understand concepts of area
measurement.
A
square with side length 1 unit, called “a unit square,”
is said to have “one square unit” of area, and can be
used to measure area.
A
plane figure which can be covered without gaps or overlaps by Recognize
area as additive. Find areas of rectilinear figures by decomposing
them into non-overlapping rectangles and adding the areas of the
non-overlapping parts, applying this technique to solve real world
problems.

Geometric
measurement: recognize perimeter as an attribute of plane figures
and distinguish between linear and area measures.

Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
