##### Spiral Review TEKS

Multiplication and Division – Whole Numbers, Fractions, Decimals – Problem Solving

• 5.3I represent and solve multiplication of a whole number and a fraction that refers to the same whole using objects and pictorial models, including area models S
• 5.3J  represent division of a unit fraction by a whole number and the division of a whole number by a unit fraction such as 1/3 ÷ 7 and 7 ÷ 1/3 using objects and pictorial models, including area models S
• 5.3L divide whole numbers by unit fractions and unit fractions by whole numbers R
• 5.3D represent multiplication of decimals with products to the hundredths using objects and pictorial models, including area models S
• 5.3E solve for products of decimals to the hundredths, including situations involving money, using strategies based on place-value understandings, properties of operations, and the relationship to the multiplication of whole numbers R
• 5.3F represent quotients of decimals to the hundredths, up to four-digit dividends and two-digit whole number divisors, using objects and pictorial models, including area models S
• 5.3G solve for quotients of decimals to the hundredths, up to four-digit dividends and two-digit whole number divisors, using strategies and algorithms, including the standard algorithm R
