In this Grade 1 math assessment unit, students encounter a variety of problems with numbers zero to ten, focusing on basic arithmetic operations. Along with counting and subtracting smaller numbers, students will encounter pattern recognition and simple number bond problems. These exercises emphasize counting and visual representation through images, requiring students to add or subtract by counting animals or objects. Students also solve missing number problems in equations and determine what numbers can be combined to create a specific sum. Many problems involve selecting the correct operation to reach a given number. In addition, the unit addresses counting in sequences, such as by twos or threes, and providing the next number in the sequence. The common core skills focused on in this unit include developing an understanding of addition, subtraction, number sense, and recognizing patterns.
