This set of 145 translucent interlocking base ten pieces consists of 100 blue units, 30 red longs and 15 yellow flats. The pieces interlock together for easy stacking of the blocks, to avoid them falling or sliding off. They are in the same colour as the rest of the Teachables Base Ten and Place Value range, to allow you to mix and match with other resources.
 
The translucent pieces are made of durable plastic, for hands-on activities. They are easy to clean.
Interlocking base ten sets help students understand the concept of place value and how a multiple-digit number is built up. Students can easily visualise the value of each digit to create number sense. A great tool to help student understand abstract base ten concepts.
