Place Value and Rounding - To Thousands and Hundredths

This math unit begins with developing students' basic number sense by ordering integers in ascending order. It then progresses into a deeper exploration of place value, starting with identifying the value of digits in both two-digit and more complex numbers. As students become more familiar with the structure and importance of place positioning, they start to tackle problems that involve missing number concepts, utilizing their skills in basic addition and numeracy. The midpoint of the unit focuses on rounding whole numbers to the nearest ten and expands students' ability to order three integers. From there, the unit shifts towards converting between expanded forms to normal forms of numbers, enhancing understanding not only with whole numbers but also with decimal numbers up to the thousandths place. The concluding sections of the unit integrate skills in converting and comparing decimal and whole numbers, emphasizing precision in understanding decimal placements and expressing numbers in different forms like expanded words. The comprehensive practice solidifies foundational place value concepts and rounding skills essential for proficient numerical manipulation and comparison in real-world contexts.
