Mathematics
Cyas wrote large numbers in long form by separating them into thousands, hundreds, tens, and ones. This helped Cyas connect each digit’s position to its value, such as understanding that a digit in the thousands place represents a different amount from the same digit in the ones place. Cyas practiced expressing a number as the sum of its place-value parts. This work strengthened Cyas’s understanding of place value and the structure of multi-digit numbers.
Tips
Tips — Build on Cyas’s place-value practice by using digit cards to create numbers and sort them from smallest to largest. Try a “number detective” activity: choose a number and describe its thousands, hundreds, tens, and ones clues for someone else to solve. Cyas could also model a number with bundles of craft sticks or base-ten blocks, then write its expanded form. To make the learning meaningful, look for large numbers on calendars, signs, or book pages and break them into place-value parts together.
