### Suggested Time Frame: 13 Instructional Days

##### Focus TEKS

Prime and Composite Numbers

• 5.4A identify prime and composite numbers; – S RC1

Order of Operations

• 5.4F simplify numerical expressions that do not involve exponents, including up to two levels of grouping; – R RC1
• 5.4E describe the meaning of parentheses and brackets in a numeric expression; – S RC1
##### Numeracy TEKS

Grade 3 – 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 Decimal Place Value to Hundredths

• 4.2B represent the value of the digit in whole numbers through 1,000,000,000 and decimals to the hundredths using expanded notation and numerals; – R RC1 [focus is on decimal place value in this unit, though numbers can extend up to review whole number place value as well]
• 4.2E represent decimals, including tenths and hundredths, using concrete and visual models and money; – S RC1
• 4.2F compare and order decimals using concrete and visual models to the hundredths; – S RC1
• 4.2G relate decimals to fractions that name tenths and hundredths; – R RC1
• 4.2H determine the corresponding decimal to the tenths or hundredths place of a specified point on a number line. – S RC1
• 4.3G represent fractions and decimals to the tenths or hundredths as distances from zero on a number line. – S RC1
