In this lesson, students work to know the number names and the count sequence. They conduct an exploration of decomposing numbers to 100 on the Rekenrek. Students count given numbers on their personal Rekenreks, and identify a corresponding teen number when ten is added to the given number. They count these numbers both the regular way and the Say Ten way, and identify the two parts of a teen number 1 ten and some additional ones.
