The Humble ISD Elementary Math Model encompasses a balanced approach to developing mathematical fluency, conceptual understanding and mathematical reasoning. Math is connected to real life situations and requires students to communicate about their thinking as required by state standards. The principles of algebraic thinking are embedded within the math model framework and require students to use properties as well as place value to solve computational problems.



    Third Grade


    What student will do in the classroom and beyond:

    * Demonstrate the understanding of the ten-to-one relationships among ones, tens, hundreds & thousands.

    * Use mathematical processes to acquire & demonstrate

    mathematical understanding through communicating mathematical ideas, problem solving, & selecting & using appropriate tools.

    * Represent & compare whole numbers & understand relationships related to place value to the hundreds thousands place, compose & decompose numbers up to 100,000, & compare & order using symbols.

    * Represent & explain fractional units greater than zero & less than or equal to one with denominators of 2, 3, 4, 6, & 8 using concrete objects & pictorial models, including strip diagrams & number lines.

    * Solve problems involving partitioning an object or a set of objects to represent equivalent fractions with denominators of 2, 3, 4, 6, & 8. Compare two fractions having the same numerator or denominator in problems by reasoning about their sizes & justifying

    the conclusion using symbols, words, objects, & pictorial models.

    *Develop & use strategies & methods for whole number

    computations in order to solve one step & multi-step problems with efficiency & accuracy.

    * Add & subtract within 1,000 using strategies based on place value, properties of operations, & the relationship between addition & subtraction. Round to the nearest 10 or 100 or use compatible numbers to estimate sums & differences.

    * Represent multiplication facts by using repeated addition, equalized groups, arrays, area models, equal jumps on a number line, & skip counting. Recall facts to multiply up to 10 by 10 with automaticity & recall the corresponding division facts.

    * Use strategies & algorithms, including the standard algorithm, to multiply a two-digit number by a one-digit number. Strategies may include mental math, partial products, & the commutative, associative, & distributive properties.

    * Solve one-step & two-step problems involving multiplication &

    division within 100 using strategies based on objects; pictorial models, including arrays, area models, & equal groups; properties of operations; or recall of facts. 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.

    * Represent real-world relationships using number pairs in a table & verbal descriptions. Use the relationship to describe comparisons & determine the unknown whole number in a multiplication or division.

    * Classify & sort two-dimensional & three-dimensional figures according to their attributes to develop generalizations about their properties.

    * Determine the area of rectangles with whole number side lengths in problems using multiplication.

    * Determine the area of rectangles with whole number side lengths in problems using multiplication, determine when it is appropriate to use measurements of liquid volume (capacity) or weight.

    * Summarize & solve multi-step problems for collecting, organizing, displaying, & interpreting data.

    * Manage one's financial resources effectively for lifetime financial security.
