Numeracy TEKS

Building Fluency with Multiplication and Division Facts

  • 3.4F recall facts [twos, fours, fives, eights, and tens facts in this unit] to multiply up to 10 by 10 with automaticity and recall the corresponding division facts;- S RC2 [Including the Use-Ten and Doubling Strategies for Multiplication; Including the Think Multiplication Strategy for Division]
    • 3.4D determine the total number of objects when equally-sized groups of objects are combined or arranged in arrays up to 10 by 10 [arrays representing twos, fours, fives, eights, and tens facts in this unit]; – S RC2
    • 3.4E represent multiplication facts [twos, fours, fives, eights, and tens facts in this unit] by using a variety of approaches such as repeated addition, equal-sized groups, arrays, area models, equal jumps on a number line, and skip counting; – S RC2
    • 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; – S RC2
Spiral Review TEKS

Grade 4 Fractions

  • Grade 4 Representing Fractions
    • 4.3A represent a fraction a/b as a sum of fractions 1/b, where a and b are whole numbers and b > 0, including when a > b; – S RC1
    • 4.3B decompose a fraction in more than one way into a sum of fractions with the same denominator using concrete and pictorial models and recording results with symbolic representations; – S RC1
  • Grade 4 Equivalence – Fractions
    • 4.3C determine if two given fractions are equivalent using a variety of methods; – S RC1
    • 4.3G represent fractions and decimals to the tenths or hundredths as distances from zero on a number line. – S RC1
  • Grade 4 Comparisons – Fractions
    • 4.3D compare two fractions with different numerators and different denominators and represent the comparison using the symbols >, =, or <; – R RC1
  • Grade 4 Adding and Subtracting – Fractions
    • 4.3E represent and solve addition and subtraction of fractions with equal denominators using objects and pictorial models that build to the number line and properties of operations; – R RC2
    • 4.3F evaluate the reasonableness of sums and differences of fractions using benchmark fractions 0, 1/4, 1/2, 3/4, and 1, referring to the same whole; and – S RC2
