Base Ten Blocks are an essential educational tool used in Year 2 to help students understand number and place value, specifically for representing numbers between 21 and 99. These blocks come in two primary forms: units and rods. A unit is the smallest block and signifies the number one, while a rod is composed of ten units, representing the number ten. This visual and tactile method of teaching allows children to build a concrete understanding of numbers by combining these blocks to form various two-digit numbers.

For instance, a combination of rods and units can be used to represent numbers such as 24, which would be shown as 2 tens (rods) and 4 units. Worksheets and flashcards are provided to reinforce this concept, challenging students to represent numbers using base ten blocks and to write the corresponding numeral and word form. These resources serve as a practical way for children to engage with numbers, enhancing their ability to visualize and understand the value of tens and ones in a number. Through hands-on activities and visual aids, students develop a stronger grasp of numerical concepts within the base ten system.
