The Number Line (to 20) WORKSHEET

Suitable for Grades: 1st Grade, 2nd Grade

CCSS: 1.OA.C.6, 2.NBT.A.2

CCSS Description: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

Count within 1000; skip-count by 5s, 10s, and 100s.

The Number Line (to 20) WORKSHEET DESCRIPTION

Introduce students to the number line to 20 with this worksheet. Here students will: identify numbers on number lines, fill blanks, skip count in 2s and 5s and estimate the position of numbers on number lines with no interval markers.
