Item description

3rd Grade Math Worksheets PDF file which consists of 10 units. Ideas for the worksheets in this resource include: independent math work packets, work book, homework, busy work, and supplement for lesson plans in a guided curriculum. Includes around 400 pages of varying activities and a small fraction of those may require the use of glue, scissors, and colors. Each unit has its very own cover followed by a contents page that shows which TEKS standards are being covered in that specific unit.

What each unit will cover:

✅Unit 1: 3.2A – Compose and decompose numbers up to 100,000 as a sum of so many ten thousands, so many hundreds, so many tens, and so many ones using objects, pictorial models, and numbers, including expanded notations as appropiate.

3.2D – Compare and order whole numbers up to 100,000 and represent comparisons using the symbols

✅Answer key

✅Unit 2: 3.4A – Solve with fluency one-step and two-step problems involving addition and subtraction within 1,000 using strategies based on place value, properties of operations, and the relationship between addition and subtraction.

3.4B – Round to the nearest 10 or 100 or use compatible numbers to estimate solutions to addition and subtraction problems.

✅Answer key

✅Unit 33.8A – Summarize a data set with multiple categories using a frequency table, dot plot, pictograph, or bar graph with scaled intervals.

3.8B – Solve one and two-step problems using categorical data represented with a frequency table, dot plot, pictograph, or bar graph with scaled intervals.

✅Answer key

✅Unit 43.4D – Determine the total number of objects when equally-sized groups of objects are combined or arranged in arrays up to 10 by 10.

3.4E – Represent multiplication facts by using a variety of approaches such as repeated addition, equal-sized groups of objects are combined or arranged in arrays up 10 by 10.

3.4F – Recall facts to multiply up to 10 by 10 with automaticity and recall the corresponding division facts.

3.4H – Determine the number of objects in each group when a set of objects is partitioned into equal shares or a set of objects is shared equally.

3.4I – Determine if a number is even or odd using divisibility rules.

3.4J – Determine a quotient using the relationship between multiplication and division.

3.5D – Determine the unknown whole number in a multiplication or division equation relating three whole numbers when the unknown is either a missing factor or product.

✅Answer key

✅Unit 53.4G – Use strategies and algorithms, including the standard algorithm, to multiply a two digit number by a one digit number. Strategies may include mental math, partial products, and the commutative, associative, and distributed properties.

3.4K – Solve one-step and two-step problems involving multiplication and division within 100 using strategies based on objects; pictorial models, including arrays, area models, and equal groups; properties of operations; or recall of facts.

✅Answer key

✅Unit 63.6A – Classify and sort two- and three-dimensional solids, including cones, cylinders, spheres, triangular and rectangular prisms, and cubes, based on atributes using formal geometric language.

3.6B – Use atributes to recognize rhombuses, parallelograms, trapezoids, rectangles, and squares as examples of quadrilaterals and draw examples of quadrilaterals that do not belong to any of these subcategories.

✅Answer key

✅Unit 73.6C – Determine the area of rectangles with whole number side lenghts in problems using multiplication related to the number of rows times the number of unit squares in each row.

3.7B – Determine the perimeter of a polygon or a missing lenght when given perimeter and remaining side lenghts in problems

✅Answer key

✅Unit 83.3A – Represent fractions greater than zero and less than or equal to one with denominators of 2, 3, 4, 6, and 8 using concrete objects and pictorial models, including strip diagrams and number lines.

3.3B – Determine the corresponding fraction greater than zero and less than or equal to one with denominators of 2,3,4,6, and 8 given a specified point on a number line.

3.3C – Explain that the unit fraction 1/b represents the quantity formed by one part of a whole that has been partitioned into b equal parts where b is a non-zero whole number.

3.3D – Solve problems involving partitioning an object or a set of objects among two or more recipients using pictorial representations of fractions with denominators of 2, 3, 4, 6, and 8.

3.7A – Represent fractions of halves, fourths, and eighths as distances from zero on a number line.

✅Answer key

✅Unit 93.7C – Determine the solutions to problems involving addition and subtraction of time intervals in minutes, using pictorial models or tools such as a 15-minute event plus a 30-minute event equals 45 minutes.

✅Answer key

✅Unit 93.2A – Compose and decompose numbers up to 100,000 as a sum of so many ten thousands, so many hundreds, so many tens, and so many ones using objects, pictorial models, and numbers, including expanded notations as appropiate.

3.2D – Compare and order whole numbers up to 100,000 and represent comparisons using the symbols.
