Unit: 1.6

Multiples of ten

In this unit students

•  count by tens;
•  represent multiples of ten on the number line;
•  count on by ones from any multiple of ten;
•  count on and back by tens from any multiple of ten;
•  compare two-digit numbers;
•  count forward and backward by ones and tens starting from a number that is not a multiple of ten.

In this unit students work with multiples of ten. Here students count forward and backward by tens from any multiple of ten, find ten more or ten less than a given number mentally, and count on by ones from any multiple of ten. They also count forward and backward by ones and tens from numbers that are not multiples of ten. Students can use tools like an empty number line to support this work. Based on the values of tens and ones, students compare numbers using pictures, number lines, and symbols (<, >, =).
