I already know how to add, carrying!
Learn to add and subtract with carried letters using a simple method to understand the step between ones and tens. The 8 boards are rewritable to practice as many times as you want, and the base includes a number line to facilitate the calculation. It contains two systems for performing subtraction with carried by compensation and by grouping. It includes a table to work on doubles from 1 to 10 and the decomposition of the number 10. Now adding and subtracting is easy and fun!
Includes:
- 8 rewritable boards made of strong cardboard (20.5 x 16.6 cm)
- 20 circular chips of strong cardboard (2.2 cm)
- 9 circular chips made of strong cardboard (4 cm)
- 8 erasable markers
CONTENTS:
- 8 rewritable boards on both sides, to practice as many times as you want. They include a number line in the base to facilitate the calculation.
- 4 boards total:
- Obverse: Learning to add.
- Reverse: Sums to practice doubles from 1 to 10 and the decomposition of the number 10.
- 4 subtraction boards, which propose two methods to learn subtraction:
- Obverse: Learning to subtract by compensation.
- Reverse: Learning to subtract by grouping.
- 8 erasable markers
- 20 blue circular tokens, representing 1 ten
- 9 Award tickets with the illustration of a frog
The game is made of thick, resistant, very durable and high quality cardboard. The material is environmentally friendly, comes from sustainable forests, is composed of a high percentage of recycled material, and is 100% recyclable.
RECOMMENDED AGE: From 6 to 10 years old.
The game allows you to practice addition and subtraction with carried ones by means of a simple method to understand the step between units and tens.
In the case of subtraction, we have two methods to perform subtraction with carried ones: subtraction by compensation and subtraction by grouping. That way, you can practice with the method you are learning in class.
DIDACTIC OBJECTIVES:
- Learn addition and subtraction with carried letters in a visual and manipulative way.
- Work on the decomposition of the number 10.
- Improve mental agility and quick calculation.
- To develop attention and observation.
- To help to generate bases to work with the ABN Method.
