It consists of ten pink wooden blocks with the side length of 1 cm to1cm.

Direct purpose:

1, visually distinguish sizes.

2. Cultivate attention and keen observation.

Indirect purpose:

1. Develop the coordination of children's movements, vision and touch.

2. Preparation for Arithmetic Education

3. Cultivate logical thinking ability

Hint method basic hint

1, g. Continuous and vertical tower buildings

▲ The teacher showed the children the pink tower and took the smallest piece to the table.

▲ The teacher first showed the children with two fingers.

▲ Please take them piece by piece. (out of order, misplaced)

▲ For larger wooden blocks, hold the bottom with your left hand and press it with your right hand.

▲ The teacher sits on the right and asks the children to find the biggest piece, and so on.

▲ Compare it every time you take it.

▲ Show it to your child before repeated practice and know the order from big to small (from top to bottom).

▲ Pay attention to the smallest piece when returning the teaching aid.

Application prompt

1, the method of changing the order

1) Align the two sides of the square to build a tower (at this time, the smallest square can learn to control errors).

2) Inclined placement method

3) Horizontal method

2, mg. Sequential plus memory exercises

1) Prepare the table and carpet.

2) Prepare ten pieces of wood and put them on the table.

3) Please start with the largest piece of wood, move it to the carpet one by one in order of size, and build a tower one at a time.

3, the change of MG

1) Ask the children to build the tower according to G's method.

The teacher told the children to close their eyes.

3) The teacher randomly takes a piece from the inside and puts it aside.

4) Let the children open their eyes.

Where should I put this piece next to the baby? Put it back in place; If you hide what you take out, ask the children what they found. (more difficult work)

Precautions:

1. In the application prompt, the practice of comparing the smallest block (control error) cannot be carried out at the same time as the basic prompt.

2. The smallest block of wood is easy to be lost, so teachers should pay attention to the custody of teaching AIDS.

3. The bonus tower can only be paired if the sequence is not paired and used with Brownian ladder.

4. Dividend-sharing towers can be paired in the form of paper, that is, draw each piece of the pink tower with the same shape on paper (thin lines are more abstract than thick lines) and pair each piece of the pink tower with children.

The pink tower allows children to identify the size of three-dimensional space.
