  1. 苏教版四年级数学上册 找规律

  2. 数一数,填一填

  3. 说一说 ( )和( )间隔排列,两端物体是( ),中间物体是( ),( )比( )多1个。 用学具来代替相关物体,排一排、数一数,验证发现的新规律,再和同桌互相说一说这个规律。 展台一旁有7面旗,每两面旗之间有一盆花; 马路一旁有9根电线杆,每两根电线杆之间有一盏路灯; 一幢大楼有8层,每两层之间有一层台阶;

  4. 两端物体 两端物体 中间物体 马路一边有25根电线杆,每两根电线杆中间有一个广告牌。一共有多少个广告牌? 25-1=24(个) 如果有25个广告牌,那又会有多少根电线杆呢? 25+1=26(个)

  5. 2(1)把一根木料锯3次,能锯成多少段? 两端物体 两端物体 中间物体 3+1=4(段) (2)如果锯成6段,需要锯几次? 两端物体 两端物体 中间物体 6-1=5(次)

  6. 75棵

  7. 字母A和B间隔排列,已知A 有5个,B可能有( )个。
