Place value within 100 - Counting forwards and backwards within 100 - Presentation

In a series of engaging activities designed to strengthen place value understanding for children, the focus is on counting forwards and backwards within 100. The lesson incorporates the use of 10s frames and number tracks to visually support the concept of sequencing numbers. For instance, children are prompted to count forwards from 60 to 69 using 10s frames, and then determine the subsequent number they reach. This method is repeated with different starting points, encouraging the students to use the number track to count forwards to a new total, such as from 65 to 73, and then to count backwards, removing counters to find lower numbers on the number track.

Further reasoning challenges involve identifying hidden numbers on a number track, both when counting forwards and backwards, enhancing problem-solving skills. For example, students are tasked with figuring out which numbers a character named Zach has concealed between 29 and 38, or which numbers Malachi has hidden in the sequence descending from 54. Additional exercises include counting on a number line to discover obscured numbers and connecting dots in sequence to form a shape, like starting at 44 and counting forwards to reveal an arrow. The lesson culminates with independent work where students fill in missing numbers, join stars in order, and determine if certain numbers will be said when counting backwards, solidifying their understanding of place value within the centenary range.
