Teachables Multi Base Ten Longs - Numeracy Manipulatives, Set of 100

This wooden base ten longs set includes 100 durable, solid timber longs, each measuring 10 cm (L) x 1 cm (H) x 1 cm (W). These high-quality maths manipulatives serve as an essential resource for exploring place value, number relationships, and core operations. Representing the value of 10, the longs provide a clear and tangible way for students to build number fluency through hands-on learning. Used alone or in combination with other base ten components—units (S900-1), flats (S900-3), and cubes (S900-4), sold separately—they support a layered understanding of the decimal system. Students can physically manipulate and model numbers to develop their understanding of addition and subtraction of multi-digit numbers. These blocks also help reinforce the concept of grouping and exchanging in place value, a critical step in progressing toward more abstract number work. Ideal for both guided instruction and open-ended exploration, the longs can also be used to build linear structures, design repeating patterns, or solve measurement challenges such as constructing a metre using a mix of base ten pieces. With applications ranging from pattern recognition to estimation and seriation, these base ten longs are a versatile and indispensable tool for numeracy learning. Their realistic sizing and simplicity make them perfect for classroom use across primary year levels.

Educational Benefits:

• Develops strong place value understanding and the concept of tens grouping.
• Supports visualisation of number operations including regrouping and exchanging.
• Improves measurement and comparison skills through concrete modelling.
• Encourages spatial awareness, sequencing, and early algebraic thinking.

Classroom Ideas:

• Challenge students to make numbers using the fewest number of blocks.
• Use in numeracy rotations for place value, addition, or subtraction challenges.
• Incorporate into STEM tasks to build structures that meet specific length constraints.
• Facilitate pattern building activities to explore repeated addition and skip counting.

Information:

• Ages: Suitable for Foundation to Year 6
• Measurements: Each long is 10 cm (L) x 1 cm (H) x 1 cm (W)
