Pre-K-2
Students construct and identify sets of seven objects. They compare sets of up to seven items, and record a set of seven in chart form.
Pre-K-2
Students explore the number 8. They make and decompose sets of eight, write the numeral 8, and compare sets of up to eight objects.
Pre-K-2
Students construct sets of up to nine items, write the numeral 9, and record nine on a chart. They also play a game that requires identifying sets of up to nine objects.
Pre-K-2
Students explore sets of up to 10 items and practice writing the numbers 0 through 10. Students count back from 10, identify sets of up to 10 objects, and record 10 on a chart. They also construct and decompose sets of up to 10 items.
Pre-K-2
Students review this unit by creating, decomposing, and comparing sets of zero to 10 objects and by writing the cardinal number for each set.
Pre-K-2
Students construct sets of numbers up to 10, write the numerals up to 10, and count up to 10 rationally. They use ten frames and also make bean sticks.
Pre-K-2
Students use bean sticks, connecting cubes, and ten frames to construct sets of 11 and 12, record them, and compare them.
Pre-K-2
Students construct and identify sets of size 13 and size 14. They compare sets to sets of size 13 and size 14, and record the number in the sets. They decompose a set of 13 and a set of 14 in several ways.
Pre-K-2
Students explore the numbers 15 and 16. They make and decompose sets of size 15 and size 16, write the numerals 15 and 16, and compare other sets to sets of size 15 and size 16.
Pre-K-2
Students construct sets up to size 18, write the numerals 17 and 18, and model 17 and 18 with bean sticks, cubes, and ten frames.
