学具分析:
1、拿到纸片后,孩子都表示:“不会做!”
2、老师提示他们先画每个单元格的对角线,然后圈出三角形,再涂色
3、由于中间包含了平行四边形、菱形、大三角形等多种相连的造型,幼儿搞不懂。
4、最后我把所有直角三角形的黑边圈好,然后幼儿用记号笔、铅笔涂色。
5、幼儿表示没有兴趣画第二张。
改良思路:
1、黑色三角格子外面套白色的边框,让每个三角形都能凸显出来
2、每个单元格四个角坐标上添加黑色圆点,便于幼儿找到连线的位置
3、黑色三角变成彩色三角,吸引幼儿兴趣。
4、考虑到有些孩子无法模仿绘画三角边黑色线条,可以直接用程序生成一份有黑色线条的答案,幼儿照着左侧的黑白三角图案或彩色三角图案,在相应的三角形黑框内涂黑色或彩色
根据上一次黑白三角学具的教学实践,开展彩色三角块的制作:
