Number Sense - Basics

Unit 12

This math unit begins by building foundational skills in counting and number recognition through visual aids and progresses to more complex numerical operations and conceptual understandings. Early in the unit, students practice counting items in pictures and using base ten blocks for understanding tens and ones, which solidifies their grasp of basic arithmetic and place value. As the unit advances, the focus shifts to identifying numerical values on a number line and recognizing digits' place values, fostering a deeper understanding of number systems. Further, the unit introduces students to concepts of even and odd numbers initially through simple identification and later by determining the parity of subtraction results, which integrates basic arithmetic operations with number theory. Students also learn to write numbers in word form, enhancing their number sense. The unit culminates with extensive practice in skip counting, both upwards and downwards, in simple and complex patterns. This not only sharpens their skills in pattern recognition and arithmetic sequences but also lays the groundwork for understanding multiplication and division foundational concepts suitable for advancing in mathematical contexts. Through gradual progression, students develop a robust comprehension of numbers, counting, and basic operations.
